Amazon.Lambda.APIGatewayEvents.APIGatewayProxyRequest is missing methodArn parameter

[ProfessionalAmateur]

The documentation for a REQUEST type custom lambda authorizer shows there should be a parameter called methodArn in the APIGatewayProxy request but I am not seeing in in the class. I'm using the AWS SDK using .net-core3.1. Am I using the correct input class for the function handler or is the methodArn parameter missing?

namespace Amazon.Lambda.APIGatewayEvents
{
   public class APIGatewayProxyRequest
   {
      public APIGatewayProxyRequest();

      public string Resource { get; set; }
      public string Path { get; set; }
      public string HttpMethod { get; set; }
      public IDictionary<string, string> Headers { get; set; }
      public IDictionary<string, IList<string>> MultiValueHeaders { get; set; }
      public IDictionary<string, string> QueryStringParameters { get; set; }
      public IDictionary<string, IList<string>> MultiValueQueryStringParameters { get; set; }
      public IDictionary<string, string> PathParameters { get; set; }
      public IDictionary<string, string> StageVariables { get; set; }
      public ProxyRequestContext RequestContext { get; set; }
      public string Body { get; set; }
      public bool IsBase64Encoded { get; set; }

      <...SNIP...>
   }
}

Does this look like a bug? Is this the proper place to file a bug report? What else can I do, to assess the lambda authorizer for REQUESTS

Use the Custom Authorizer request?

@msimpsonnz I think that will work perfectly. I couldnt find documentation on when to use the APIGatewatyProxyRequest vs the suggested APIGatewayCustomAuthorizerRequest (albeit Im very new to lambda authorizers), is there a better location than the documentation I linked to above?

I appreciate the response!

No worries, I appreciate it’s not obvious as the models haven’t been update to reflect the name change from “Custom Authorizer” to new name of “Lambda Authorizer”
This would also reflect in searching on the web so I would use the old name for some examples
This is a great guide too
