I'm getting this.

I have a similar problem.

In my case, after sam deploy, when I run the test in the Lambda console, I get the following error:

{
  "errorMessage": "RequestId: 0d280a9a-152b-4876-998f-193e24f2d143 Error: Runtime exited with error: exit status 126",
  "errorType": "Runtime.ExitError"
}

Similar errors occur in local tests before deployment.

It seems that this sample app hasn't been updated since 2 years ago, so I'd be happy if you could update it so that the error is resolved.
