C# AWS CDK Serverless, publish new version Lambda and create new API resource

I'm new to AWS CDK and what I'm trying to accomplish (using C#) is to version my lambda function, and then create a new API resource referencing the version.
For example: The program accepts a version parameter.
internal CdkAppStack(Construct scope, string id, IStackProps props, string bucketName, string functionName, string version) : base(scope, id, props)
{
var bucket = new Bucket(this, bucketName, new BucketProps {
BucketName = bucketName
});
var handler = new Function(this, $"{functionName}Handler", new FunctionProps
{
Runtime = Runtime.DOTNET_CORE_3_1,
Code = Code.FromAsset("Lambdas\\src\\Lambdas\\bin\\Debug\\netcoreapp3.1"),
Handler = "Lambdas::Lambdas.Function::FunctionHandler",
Environment = new Dictionary<string, string>
{
["BUCKET"] = bucket.BucketName,
},
FunctionName = functionName
});
string apiName = !string.IsNullOrEmpty(version) ? $"{functionName}-{version}" : functionName;
bucket.GrantReadWrite(handler);
var api = new RestApi(this, $"{apiName}-API", new RestApiProps
{
RestApiName = $"{apiName}API",
Description = $"This service the Lambda - {functionName}.",
RetainDeployments = true
});
var getWidgetsIntegration = new LambdaIntegration(handler, new LambdaIntegrationOptions
{
RequestTemplates = new Dictionary<string, string>
{
["application/json"] = "{ \"statusCode\": \"200\" }"
}
});
string resource = !string.IsNullOrEmpty(version) ? $"execute-{version}" : "execute";
var helloWorldResource = api.Root.AddResource(resource);
var method = helloWorldResource.AddMethod("POST", getWidgetsIntegration);
}
Actual result:
It overrides the lambda and api resource.
Expected result:(version parameter is 3). Added new resource (execute-3)
AWS Console - Expected result

For the given code the process probably looks like this:
Current provisioned state includes execute-2
CDK synthesizes a Cloudformation template where execute-3 exists and execute-2 does not exist.
Cloudformation figures out that in order to reach the desired state (described in the template) it needs to delete execute-2 and provision execute-3.
If you literally want to reach what you are describing you will have to add resources and not delete previously provisioned ones (say write a loop that runs over 1..version and adds all past versions)
Another (less recommendable) option is to use a deletion policy. This way you can hint cloudformation not the delete execute-2 (the downside here is that execute-2's lifecycle is no longer managed by any stack --> you will have to manage changes to it manually)

Usage of GetApiKeys in Amazon SDK

I am trying to get the total count of api keys in my API gateway via SDK.
However I am unsure on the proper implementation of the parameters that the GetApiKeysRequest takes in. My main objective is to get the count of all API keys that are already existing for my account.
The code I have so far looks like this :
class Program
{
public static void Main(string[] args)
{
var awsUserAccessKey = "xxxxx";
var awsUserSecretKey = "yyyyyyyyyyy";
var regionEndpoint = "us-west-2";
var keysInRepository = new GetApiKeysRequest
{
CustomerId = "",
IncludeValues = true||false,
Limit=0,
NameQuery = "",
Position = ""
};
var client = new AmazonAPIGatewayClient(awsUserAccessKey, awsUserSecretKey, regionEndpoint);
var apiKeys =client.GetApiKeys(keysInRepository);
Console.Read();
}
}
This code throws an error saying that The security token included in the request is invalid (Amazon.APIGateway exception).I am unsure on how to set the parameters for this request.

Because the AmazonAPIGatewayClient you are using as described here takes three string arguments and the last one is awsSessionToken i think you are confusing with this one which takes as third argument RegionEndpoint
Do something like that instead :
var client = new AmazonAPIGatewayClient(awsUserAccessKey, awsUserSecretKey, RegionEndpoint.USWest2);

For someone looking for a solution to similar problems, this worked :
var awsUserAccessKey = "xxxx";
var awsUserSecretKey = "yyyyy";
var regionEndpointName = "us-west-2";
var regionEndpoint = RegionEndpoint.GetBySystemName(regionEndpointName);
var keysInRepository = new GetApiKeysRequest
{
Limit = 500
};
//define the key and its fields
var client = new AmazonAPIGatewayClient(awsUserAccessKey, awsUserSecretKey, regionEndpoint);
var apiKeys = client.GetApiKeys(keysInRepository);
Console.WriteLine("Current number of api keys:{0}", apiKeys.Items.Count);

So the issue im having is when i try to run the program i get an error at this line
sbasedrmTableAdapter.Insert(drm_key_id);
and the error i receive is:
Error CS7036 There is no argument given that corresponds to the
required formal parameter 'drm_key' of
'sbase_drm_keysTableAdapter.Insert(string, string, string, string)'
How can i solve this error

It looks like you are trying to call a method that requires 4 strings as parameters with just one parameter. Try supplying the correct parameters to the method.
Your problem looks quite similar to: OOP inheritance and default constructor

RavenDB throws a JSON deserialisation error when retrieving document

I've just completed a round of refactoring of my application, which has resulted in my removing a project that was no longer required and moving its classes into a different project. A side effect of this is that my User class, which is stored in RavenDB, has a collection property of a type moved to the new assembly. As soon as I attempt to query the session for the User class I get a Json deserialisation error. The issue is touched upon here but the answers don't address my issue. Here's the offending property:
{
"OAuthAccounts": {
"$type": "System.Collections.ObjectModel.Collection`1[
[Friendorsement.Contracts.Membership.IOAuthAccount,
Friendorsement.Contracts]], mscorlib",
"$values": []
},
}
OAuthAccounts is a collection property of User that used to map here:
System.Collections.ObjectModel.Collection`1[[Friendorsement.Contracts.Membership.IOAuthAccount, Friendorsement.Contracts]]
It now maps here:
System.Collections.ObjectModel.Collection`1[[Friendorsement.Domain.Membership.IOAuthAccount, Friendorsement.Domain]]
Friendorsement.Contracts no longer exists. All of its types are now in Friendorsement.Domain
I've tried using store.DatabaseCommands.StartsWith("User", "", 0, 128) but that didn't return anything.
I've tried looking at UpdateByIndex but not got very far with it:
store.DatabaseCommands.UpdateByIndex("Raven/DocumentsByEntityName",
new IndexQuery {Query = "Tag:Users"},
new[]
{
new PatchRequest { // unsure what to set here }
});
I'm using Raven 2.0

Below is a simple sample application that shows you the patching Metadata. While your example is a little different this should be a good starting point
namespace SO19941925
{
internal class Program
{
private static void Main(string[] args)
{
IDocumentStore store = new DocumentStore
{
Url = "http://localhost:8080",
DefaultDatabase = "SO19941925"
}.Initialize();
using (IDocumentSession session = store.OpenSession())
{
for (int i = 0; i < 10; i++)
{
session.Store(new User {Name = "User" + i});
}
session.SaveChanges();
}
using (IDocumentSession session = store.OpenSession())
{
List<User> users = session.Query<User>().Customize(x => x.WaitForNonStaleResultsAsOfNow()).ToList();
Console.WriteLine("{0} SO19941925.Users", users.Count);
}
Operation s = store.DatabaseCommands.UpdateByIndex("Raven/DocumentsByEntityName",
new IndexQuery {Query = "Tag:Users"},
new ScriptedPatchRequest
{
Script = #"this['#metadata']['Raven-Clr-Type'] = 'SO19941925.Models.User, SO19941925';"
}, true
);
s.WaitForCompletion();
using (IDocumentSession session = store.OpenSession())
{
List<Models.User> users =
session.Query<Models.User>().Customize(x => x.WaitForNonStaleResultsAsOfNow()).ToList();
Console.WriteLine("{0} SO19941925.Models.Users", users.Count);
}
Console.ReadLine();
}
}
internal class User
{
public string Name { get; set; }
}
}
namespace SO19941925.Models
{
internal class User
{
public string Name { get; set; }
}
}
UPDATE: Based on the initial answer above, here is the code that actually solves the OP question:
store.DatabaseCommands.UpdateByIndex("Raven/DocumentsByEntityName",
new IndexQuery {Query = "Tag:Users"},
new ScriptedPatchRequest
{
Script = #"this['OAuthAccounts']['$type'] =
'System.Collections.ObjectModel.Collection`1[
[Friendorsement.Domain.Membership.IFlexOAuthAccount,
Friendorsement.Domain]], mscorlib';",
}, true
);

Here are two possible solutions:
Option 1: Depending on what state your project is in, for example if you are still in development, you could easily just delete that collection out of RavenDB from the Raven Studio and recreate all those User documents. All the new User documents should then have the correct class name and assembly and should then deserialize correctly. Obviously, if you are already in production, this probably won't be a good option.
Option 2: Depending on how many User documents you have, you should be able to manually edit each one to specify the correct C# class name and assembly, so that they will be deserialized correctly. Again, if you have too many objects to manually modify, this may not be a good option; however, if there are just a few, it shouldn't be too bad to open each one up go to the metadata tab and paste the correct value for "Raven-Entity-Name" and "Raven-Clr-Type".

I ended up doing this:
Advanced.DatabaseCommands.UpdateByIndex(
"Raven/DocumentsByEntityName",
new IndexQuery {Query = "Tag:Album"},
new []{ new PatchRequest() {
Type = PatchCommandType.Modify,
Name = "#metadata",
Nested= new []{
new PatchRequest{
Name= "Raven-Clr-Type",
Type = PatchCommandType.Set,
Value = "Core.Model.Album, Core" }}}},
false);

How to get all the documents in a folder in Google Docs

I can get all the documents in Google Docs using
public DocumentsFeed GetDocs()
{
DocumentsListQuery query = new DocumentsListQuery();
DocumentsFeed feed = service.Query(query);
return feed;
}
But how can I get the documents in a particular folder? I wan to discover the list of folders and then populate the folders in a tree view. On selection of a folder, I shall like to get the documents in that folder.
To get the folder, I am using
public DocumentsFeed GetFolders()
{
FolderQuery query = new FolderQuery("root"); //http://docs.google.com/feeds/documents/private/full
DocumentsFeed feed = service.Query(query);
return feed;
}
For the service, I am using private DocumentsService service;
Can somebody help?

Another guy using the API has described how he does it:
var docService = new DocumentsService("company-app-version");
docService.setUserCredentials("username", "password");
using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Documents;
// snipped method declaration etc
var docService = new DocumentsService("company-app-version");
docService.setUserCredentials("username", "password");
var folderList = docService.Query(new FolderQuery());
var fLinks = folderList.Entries.Select(e =>
new
{
// note how to get the document Id of the folder
Id = DocumentsListQuery.DocumentId(e.Id.AbsoluteUri),
Name = e.Title.Text
});
foreach (var folder in fLinks)
{
Console.WriteLine("Folder {0}", folder.Name);
var fileList = docService.Query(
new SpreadsheetQuery()
{
// setting the base address to the folder's URI restricts your results
BaseAddress = DocumentsListQuery.folderBaseUri + folder.Id
});
foreach (var file in fileList.Entries)
{
Console.WriteLine(" - {0}", file.Title.Text);
}
}
Source:
http://jtnlex.com/blog/2010/06/09/google-docs-api-get-all-spreadsheetsdocs-in-a-folder/

Here's how :
instead of typing the name of the folder , use the resourceID of the folder query = new FolderQuery(FolderEntry.ResourceId);
But first you need to get ALL documents in the root and enable showing folders : query.ShowFolders = true; , that's how you get the resourceId's of the docs in the root and
folders!
Hope this helps !
