Xero invoice send email using standard .NET library

Here I have created my project on the standard .NET library to GET/POST invoices. But as I want to email the invoice to which it's being created on that name. Here is my sample code below to create invoice.
public async Task<ActionResult> Create(string Name, string LineDescription, string LineQuantity, string LineUnitAmount, string LineAccountCode)
{
var xeroToken = TokenUtilities.GetStoredToken();
var utcTimeNow = DateTime.UtcNow;
var serviceProvider = new ServiceCollection().AddHttpClient().BuildServiceProvider();
var httpClientFactory = serviceProvider.GetService<IHttpClientFactory>();
XeroConfiguration XeroConfig = new XeroConfiguration
{
ClientId = ConfigurationManager.AppSettings["XeroClientId"],
ClientSecret = ConfigurationManager.AppSettings["XeroClientSecret"],
CallbackUri = new Uri(ConfigurationManager.AppSettings["XeroCallbackUri"]),
Scope = ConfigurationManager.AppSettings["XeroScope"],
State = ConfigurationManager.AppSettings["XeroState"]
};
if (utcTimeNow > xeroToken.ExpiresAtUtc)
{
var client = new XeroClient(XeroConfig, httpClientFactory);
xeroToken = (XeroOAuth2Token)await client.RefreshAccessTokenAsync(xeroToken);
TokenUtilities.StoreToken(xeroToken);
}
string accessToken = xeroToken.AccessToken;
string xeroTenantId = xeroToken.Tenants[0].TenantId.ToString();
//string xeroTenantId = xeroToken.Tenants[1].TenantId.ToString();
var contact = new Contact();
contact.Name = Name;
var line = new LineItem()
{
Description = LineDescription,
Quantity = decimal.Parse(LineQuantity),
UnitAmount = decimal.Parse(LineUnitAmount),
AccountCode = LineAccountCode
};
var lines = new List<LineItem>() { line };
//var lines = new List<LineItem>();
//for (int j = 0;j < 5;j++)
//{
// lines.Add(line);
//}
var invoice = new Invoice()
{
Type = Invoice.TypeEnum.ACCREC,
Contact = contact,
Date = DateTime.Today,
DueDate = DateTime.Today.AddDays(30),
LineItems = lines
};
var invoiceList = new List<Invoice>();
invoiceList.Add(invoice);
var invoices = new Invoices();
invoices._Invoices = invoiceList;
var AccountingApi = new AccountingApi();
var response = await AccountingApi.CreateInvoicesAsync(accessToken, xeroTenantId, invoices);
RequestEmpty _request = new RequestEmpty();
//trying this method to send email to specified invoice....
//var test = await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, Guid.NewGuid(), null);
var updatedUTC = response._Invoices[0].UpdatedDateUTC;
return RedirectToAction("Index", "InvoiceSync");
}
Now as I learned that Xero allows sending email to that specified invoice, here is a link which I learned.
https://developer.xero.com/documentation/api/invoices#email
But as try to find method in the .NET standard library for Xero I stumble upon this method.
var test = await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, Guid.NewGuid(), null);
How can I use this method to send email to a specified invoice ..?
It throws me an error regarding Cannot assign void to an implicitly-typed variable.
There is another method also in this library.
var test2 = await AccountingApi.EmailInvoiceAsyncWithHttpInfo(accessToken, xeroTenantId, Guid.NewGuid(), null);
As Guid.NewGuid() i have used is for only testing will add created GUID when I understand how these two methods operate.
Update 1:
Here is the method second method i used.
await AccountingApi.EmailInvoiceAsyncWithHttpInfo(accessToken, xeroTenantId, Guid.NewGuid(), null)
Update 2:
Here is the code i used.
public async Task EmailInvoiceTest(string accessToken,string xeroTenantId,Guid invoiceID, RequestEmpty requestEmpty)
{
var AccountingApi = new AccountingApi();
await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, invoiceID, requestEmpty).ConfigureAwait(false);
}

The return type of method EmailInvoiceAsync seems to be Task with return type void. If you await the task, there is no return type which could be assigned to a variable. Remove the variable assignment and pass a valid argument for parameter of type RequestEmpty to solve the problem.
RequestEmpty requestEmpty = new RequestEmpty();
await AccountingApi.EmailInvoiceAsync(accessToken, xeroTenantId, Guid.NewGuid(), requestEmpty);
For an example test see here
IMPORTANT: According to the documentation (see section Emailing an invoice) the invoice must be of Type ACCREC and must have a valid status for sending (SUMBITTED, AUTHORISED or PAID).

Lead Ads Testing Tool - Server failure (102)

I'm trying to get Facebook leadgen ad data.
1-)As seen below, facebook sends the data to me successfully and I receive it successfully.

2-)But the submissions I made on just this page do not come. What could be the reason for this?
Failed Process img
*But only the opinions I made on this page are not coming. What could be the reason for this?
Facebook doesn't even post. As seen in the picture, Server failure (102) information is displayed. What is the reason of this?

Microsoft Teams bot - link unfurling auth flow

Can't find good example of auth flow for link unfurling. I managed to run oauth flow using this example. But after user provided login and password and bot hits OnTeamsAppBasedLinkQueryAsync second time GetUserTokenAsync still returns null. So I don't follow where should I get then token from when auth flow is finished. Should I persist it somehow? Will Teams send me the token on every request or how it should work?
So in my case following code always returns null:
var tokenResponse = await (turnContext.Adapter as IUserTokenProvider)
.GetUserTokenAsync(turnContext, _connectionName, default(string),
cancellationToken: cancellationToken);

It seems the 'state' field is not present on AppBasedLinkQuery. When the auth flow completes, OnTeamsAppBasedLinkQueryAsync will be called again and the turnContext.Activity.Value will contain the url and the 'state' (or magic code). We will get this field added to AppBasedLinkQuery (created an issue here: microsoft/botbuilder-dotnet#3429 ).
A workaround is to retrieve the state/magiccode directly from the Activity.Value Something like:
protected async override Task<MessagingExtensionResponse> OnTeamsAppBasedLinkQueryAsync(ITurnContext<IInvokeActivity> turnContext, AppBasedLinkQuery query, CancellationToken cancellationToken)
{
var magicCode = string.Empty;
var state = (turnContext.Activity.Value as Newtonsoft.Json.Linq.JObject).Value<string>("state");
if (!string.IsNullOrEmpty(state))
{
int parsed = 0;
if (int.TryParse(state, out parsed))
{
magicCode = parsed.ToString();
}
}
var tokenResponse = await(turnContext.Adapter as IUserTokenProvider).GetUserTokenAsync(turnContext, _connectionName, magicCode, cancellationToken: cancellationToken);
if (tokenResponse == null || string.IsNullOrEmpty(tokenResponse.Token))
{
// There is no token, so the user has not signed in yet.
// Retrieve the OAuth Sign in Link to use in the MessagingExtensionResult Suggested Actions
var signInLink = await(turnContext.Adapter as IUserTokenProvider).GetOauthSignInLinkAsync(turnContext, _connectionName, cancellationToken);
return new MessagingExtensionResponse
{
ComposeExtension = new MessagingExtensionResult
{
Type = "auth",
SuggestedActions = new MessagingExtensionSuggestedAction
{
Actions = new List<CardAction>
{
new CardAction
{
Type = ActionTypes.OpenUrl,
Value = signInLink,
Title = "Bot Service OAuth",
},
},
},
},
};
}
var heroCard = new ThumbnailCard
{
Title = "Thumbnail Card",
Text = query.Url,
Images = new List<CardImage> { new CardImage("https://raw.githubusercontent.com/microsoft/botframework-sdk/master/icon.png") },
};
var attachments = new MessagingExtensionAttachment(HeroCard.ContentType, null, heroCard);
var result = new MessagingExtensionResult("list", "result", new[] { attachments });
return new MessagingExtensionResponse(result);
}

How to request report from c# console application using Telerik REST API

I have Telerik REST API and at client side i'm using html5 report-viewer. Report are generating successfully in a report viwer in html. Now i want to request for the reports from same API through c# console application. I have search but didn't fine any solution. Please suggest me a way how can i request a report using C# console application.
html5 report-viewer Library
Note: I'm very beginner in telerik reporting.
Update 1:
I have manage to send request to the server using this API documentation.
Telerik Document for Getting Report
on Server side i have written the CustomReportResolver . But now its now sending the InstanceId to the console client.
CustomReportResolver
public class CustomReportResolver : IReportResolver
{
public ReportSource Resolve(string reportJsonString)
{
var reportDto = JsonConvert.DeserializeObject<ReportDTO>(reportJsonString);
var connectionStringHandler = new CustomConnectionStringManager(reportDto.CompanyId);
var reportsPath = HttpContext.Current.Server.MapPath($"~/Reports/{reportDto.ReportPath}");
var sourceReportSource = new UriReportSource { Uri = reportsPath + reportDto.ReportName };
// sourceReportSource.Parameters.Add(new Telerik.Reporting.Parameter("companyId", reportDto.CompanyId));
var reportSource = connectionStringHandler.UpdateReportSource(sourceReportSource);
return reportSource;
}
}
Note if i use default ReportResolver self hosted telerik service sending the pdf report to console successfully but if i use CustomReportResolver it's not generating instanceId.
What could be the problem ?

After wasting a lot of time then found a solution how to get PDF(Or any other report format) documents from Telerik Self hosted Web Service. Following are the general steps to be followed.
Get Client Id
Get Instance Id
Get Document Id
Download Document
Below is a step wise code:
static HttpClient client = new HttpClient();
static string reportServerAddress = "http://localhost:60031/";
static string serverREStAPI = reportServerAddress + "api/";
static void Main(string[] args)
{
try
{
Console.WriteLine("Demo started");
RunAsync().Wait();
Console.WriteLine("Demo ended");
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine(ex);
Console.ReadKey();
}
}
static async Task RunAsync()
{
// readFile();
// return;
client.BaseAddress = new Uri(serverREStAPI);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/html"));

JSON serializer error with BotFramework an LUIS

StackOverflow Community!
I have a chatbot, and integrated LUIS.ai to make it smarter. One of the dialogues is about to Book an appointment with a Supervisor (Teacher)
Everything has been working fine, with literally the same code. A couple of hours ago I am experiencing some strange errors.
Exception: Type 'Newtonsoft.Json.Linq.JArray' in Assembly 'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' is not marked as serializable.
How to reproduce the error?
If the both Entity (Teacher and Date) is missing from the user's input it works FINE, the bot builds the Form, asking for missing inputs and presents the suggested meeting times.
If one of the Entity is missing it from input it will build a Form and asks for the missing Date or Teacher Entity and presents the suggested meeting times.
BUT
If the user's input contains both Entity: the Teacher and the Date too, then I am getting the error.
Here is my WebApiConfig class:
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Json settings
config.Formatters.JsonFormatter.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
config.Formatters.JsonFormatter.SerializerSettings.Formatting = Formatting.Indented;
JsonConvert.DefaultSettings = () => new JsonSerializerSettings()
{
ContractResolver = new CamelCasePropertyNamesContractResolver(),
Formatting = Newtonsoft.Json.Formatting.Indented,
NullValueHandling = NullValueHandling.Ignore,
};
// Web API configuration and services
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
I am only experiencing this error when I am trying to get an Entity from the user utterance, which is a type of builtin.dateTimeV2.
This async method is called:
//From the LUIS.AI language model the entities
private const string EntityMeetingDate = "MeetingDate";
private const string EntityTeacher = "Teacher";
[LuisIntent("BookSupervision")]
public async Task BookAppointment(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result)
{
var message = await activity;
await context.PostAsync($"I am analysing your message: '{message.Text}'...");
var meetingsQuery = new MeetingsQuery();
EntityRecommendation teacherEntityRecommendation;
EntityRecommendation dateEntityRecommendation;
if (result.TryFindEntity(EntityTeacher, out teacherEntityRecommendation))
{
teacherEntityRecommendation.Type = "Name";
}
if (result.TryFindEntity(EntityMeetingDate, out dateEntityRecommendation))
{
dateEntityRecommendation.Type = "Date";
}
var meetingsFormDialog = new FormDialog<MeetingsQuery>(meetingsQuery, this.BuildMeetingsForm, FormOptions.PromptInStart, result.Entities);
context.Call(meetingsFormDialog, this.ResumeAfterMeetingsFormDialog);
}

}
await context.PostAsync(message);
};

private async Task<IEnumerable<Meeting>> GetMeetingsAsync(MeetingsQuery searchQuery)
{
var meetings = new List<Meeting>();
//some random result manually for demo purposes
for (int i = 1; i <= 5; i++)

}
return meetings;
}
The strangest thing that this code has worked, and my shoutout and respect goes for the community on GitHub, because I think this is an awesome platform with a tons of documentation and samples.

This is known issue (also reported here and here).
Long story short, since the builtin.datetimeV2.* entities are not yet supported in BotBuilder, the Resolution dictionary of the EntityRecommendation ends up with an entry with a value of type JArray. The problem arises when you pass those entities to a FormDialog. Since the entities are a private field in the dialog and of course, as any other dialog, is being serialized, an exception is being thrown because the JArray class from Newtonsoft is not marked as serializable.
The request for adding support for datetimeV2 entities is here.
The workaround I can think of right now is to extract the value of the DateTime entity manually and assign it your Date field of your MeetingsQuery instance you are passing to the FormDialog and also to remove the DateTime entity from the result.Entities collection that you are passing to the FormDialog.
Update
This is already fixed in the SDK as you can see in this Pull Request.
