System.TypeLoadException: Method 'get_Features' #652

Closed rhysstubbs closed 3 years ago

rhysstubbs commented 4 years ago

Using the AWS Mock Lambda Test Tool to send a test request I receive the following exception:

System.TypeLoadException: Method 'get_Features' in type 'Amazon.Lambda.AspNetCoreServer.Internal.LambdaServer' from assembly 'Amazon.Lambda.AspNetCoreServer, Version=2.0.0.0, Culture=neutral, PublicKeyToken=885c28607f98e604' does not have an implementation.
   at Amazon.Lambda.AspNetCoreServer.AbstractAspNetCoreFunction`2.Start()
   at Amazon.Lambda.AspNetCoreServer.AbstractAspNetCoreFunction`2..ctor(StartupMode startupMode)
   at Amazon.Lambda.AspNetCoreServer.AbstractAspNetCoreFunction`2..ctor()
   at Amazon.Lambda.AspNetCoreServer.APIGatewayHttpApiV2ProxyFunction..ctor()
   at Some.Example.Namespace.LambdaProgram..ctor()

My configuration is very minimal, essentially a customised version of the boilerplate provided. I'm integrating with an existing .NET Core 3.1 Web API application. I'm assuming this isnt't coming rom the LambdaServer itself considering no .NET library use a convention seen in "get_Features"?

UPDATE

I cloned this repository and tested one of the .NET 3.1 blueprints, with complete success. I then took the startup, lambda entrypoint classes and example controller and tested my application again. Still no joy. I'm thinking this may be related to a particular dependency I have?

Can you share your project file?

Hi @rhysstubbs,

Good morning.

Please let me know if this is still an issue. If yes, request you to provide sample project code (with all sensitive information removed) to troubleshoot further.

Thanks, Ashish
