I keep getting the error System.Threading.Tasks.TaskCanceledException: A task was canceled when trying to any user admin operation on Firebase, using C# SDK.
Here is an example of how I am doing the call to Firebase Admin:
public static async Task<bool> SaveUserInFirebaseAsync(string email, string nome, bool emailVerified, string password, Guid uid)
{
UserRecordArgs args = new UserRecordArgs()
{
Uid = uid.ToString().ToUpper(),
Email = email,
EmailVerified = emailVerified,
DisplayName = nome,
Password = password
};
try
{
UserRecord userRecord = await FirebaseAuth.DefaultInstance.CreateUserAsync(args);
}
catch (Exception ex)
{
Logging.startFileLog(ex.ToString(), null, null, null, LogType.Error);
return false;
}
return true;
}
I dont know if its a firebase error or if I am doing the async call wrong.
Edit:
Here is the full stack trace

Below is My Code Snippet which i am using

I've been doing a bot with the Microsoft Bot Framework in C# and I encountered a problem.
The problem is that when I call "PromptDialog" to get a String from the user, in this case a password, it doesn't ask for it, it opens the "Password" method and crashes when trying to obtain that String.
Thanks for your help!
The class extends LUISDialog
PromptDialog.Text(context, resume: Password, prompt: "Enter password:");
LUIS Intent null:
[LuisIntent("")]
public async Task None(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result)
{
Boolean PassLogin;
Start(context, activity); //Does this need to be awaited?
if (!context.UserData.TryGetValue<Boolean>("PassLogin", out PassLogin)) PassLogin = false;
if (PassLogin)
{
var act = await activity;
if (act.Conversation.IsGroup != null && act.Conversation.IsGroup.Value)
{
context.Wait(MessageReceived);
}
else
{
await Nothing(context, activity, result);
}
}
else context.Wait(MessageReceived);
}
Start Method. The Start method is called by every intent from LUIS.
public async Task Start(IDialogContext context, IAwaitable<IMessageActivity> activity)
{
Boolean PassLogin, start;
if (!context.UserData.TryGetValue<Boolean>("PassLogin", out PassLogin))
{
PassLogin = false;
context.UserData.SetValue<Boolean>("PassLogin", PassLogin);
}
if (!context.UserData.TryGetValue<Boolean>("start", out start))
{
start = true;
}
if (start)
{
PromptDialog.Text(context, resume: Password, prompt: "Enter password:");
await context.PostAsync("Something"); //This prints out before going to password.
}
await GetKey(context, activity);
}
private async Task Password(IDialogContext context, IAwaitable<String> argument)
{
var response = await argument;
if (response=="test")
{
context.UserData.SetValue<Boolean>("PassLogin", true);
await context.PostAsync("Correct Password.");
if (context.UserData.Get<Boolean>("PassLogin"))
{
await context.PostAsync("Welcome");
context.UserData.SetValue<Boolean>("start", false);
}
}
else
{
context.UserData.SetValue<Boolean>("PassLogin", false);
await context.PostAsync("Incorrect password.");
}
context.Wait(MessageReceived); //Does this need to be here? (Tried with and without.)
}
This is what the error says:

As I wrote in the comments, there are a few issues that would have to be solved:
The call to the Start method must be awaited
There shouldn't be code after the call to PromptDialog.Text. That code is starting a new dialog that will continue in the ResumeAfter method once it's done
All the code after the Start call seems to depend on the ResumeAfter of the Prompt so it should be moved there.
Maybe I'm not understanding what a VirtualFileResult is, but I'm not sure why it's throwing a FileNotFoundException when the file exists. Here's the code:
if (System.IO.File.Exists(fileName))
{
FileInfo info = new FileInfo(fileName);
return File(fileName, FileUtility.GetContentType(fileName), info.Name);
}
(Edit: FileUtility.GetContentType (correctly) returns the Mime type of the file, which in my case is "application/pdf".)
Here's the exception I get: (I removed the file path)
System.IO.FileNotFoundException: Could not find file: [file path removed]
File name: '[file path removed]'

It's seemingly bugging out even though an explicit check was done for whether the file exists or not. I can also manually confirm the file exists.
Maybe I'm not understanding what a VirtualFileResult is (File method returns this). On the documentation here it doesn't really describe what it is.
I'm using ASP.NET 5 RC1.
The method you're looking for is PhysicalFile():
return PhysicalFile(fileName, FileUtility.GetContentType(fileName), info.Name);
Beware, don't use a caller-supplied path with this.
The VirtualFileResult class needs the virtual path to the file in its constructor.
This means you need to provide the path relative to the wwwroot folder because it use HostingEnvironment's WebRootFileProvider.
private IFileProvider GetFileProvider(IServiceProvider requestServices)
{
if (FileProvider != null)
{
return FileProvider;
}
var hostingEnvironment = requestServices.GetService<IHostingEnvironment>();
FileProvider = hostingEnvironment.WebRootFileProvider;
return FileProvider;
}
}
Check the code on github
No luck with File("index.html") or File("~/index.html"), Virtualfileresult throws NotFound.
My solution was to use Microsoft.AspNetCore.Mvc.ControllerBase
method File(Stream fileStream...) :
public virtual FileStreamResult File(Stream fileStream,
string contentType, string fileDownloadName);
Index controller sample:
using System.IO;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
public class IndexController : Controller
{
ILoggerFactory Logger;
public IndexController(ILoggerFactory loggerFactory)
{
Logger = loggerFactory;
}
static string sep = Path.DirectorySeparatorChar.ToString();
[HttpGet("/index")]
[HttpGet("/")]
public IActionResult Index()
{
var log = Logger.CreateLogger("trace");
var path = $"{Startup.RootPath}{sep}index.html";
log.LogWarning(path);
Stream fileStream = new System.IO.FileStream(path, FileMode.Open);
return File(fileStream, "text/html");
}
}
// AspnetCore version 1.1.1 :
// <TargetFramework>netcoreapp1.1</TargetFramework>
// <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="1.1.1" />
Your VirtualFileResult must be a relative path from the application's wwwroot.
return File("~/foo.js","text/javascript")
is going to point to wwwroot/foo.js
I have a simple ASP.NET vNext project, with ASP Identity and SimpleInjector configured (according to http://simpleinjector.readthedocs.org/en/latest/aspnetintegration.html).
Registration works fine, however when I try to log in I get an error:

I get this exception intermittently in my asp.net mvc 5 c# web application:
Server cannot append header after HTTP headers have been sent.
It just happens uploading images to S3 method (Web Api Controller).
The presendrequestheaders in Global.asax
protected void Application_PreSendRequestHeaders(object sender, EventArgs e)
{
HttpApplication app = sender as HttpApplication;
if (app != null &&
app.Context != null)
{
app.Context.Response.Headers.Remove("Server");
}
}
The method that trigger the error:
[HttpPost]
[Route("UploadImageJSON")]
public IHttpActionResult UploadImageJSON(HttpRequestMessage request)
{
var httpRequest = HttpContext.Current.Request;
// Check if files are available
if (httpRequest.Files.Count != 1) return BadRequest();
var postedFile = httpRequest.Files[0];
var contentType = postedFile.ContentType;
if (!contentType.Contains("image"))
{
return StatusCode(HttpStatusCode.NotAcceptable);
}
var keyUploadFiles = Constants.UrlS3Amazon +
S3.UploadToS3WithStream(postedFile.InputStream, contentType);
return Json(JsonConvert.SerializeObject(keyUploadFiles));
}
EDIT: More information... I have my Web App hosted in Elastic BeanStalk with a load balancer, the load balancer has installed a SSL Certificate, and the connection between the load balancer and the EC2 instances are in ports 80. Maybe it could be helpful.
The Elmah log:

Thanks!!
have you tried with removing app.Context.Response.Headers.Remove("Server"); i think there is this is the issue?
