Can't debug Lambda declared as a "AWS::Lambda::Function"

[noesnaterse]

Describe the bug

After installing the toolkit, I wanted to debug a Lambda function. This doesn't work, but I don't know the exact error because it isn't there completely.

This is problematic, because how am I going to fix that, if I cannot read the error message.

To reproduce

1. Download the test project https://github.com/noesnaterse/aws-sam
2. In PyCharm go to Run -> Edit configurations
3. Copy the information as can be seen in this screen
4. Press run
5. Get the error

Expected behavior The Lambda function would just run

It actually looks like we've never supported this properly for AWS::Lambda::Function.

We're expecting Code to point to a file path, which doesn't make sense. The following should be enough to start a debug session against your sample project

  dummy:
    Type: AWS::Lambda::Function
    Properties:
      Code: lambda_handler
      Handler: handler.main
      Runtime: python3.9
