You can now browse to the above endpoints to invoke your functions. You do not
need to restart/reload SAM CLI while working on your functions, changes will be
reflected instantly/automatically. If you used sam build before running local
commands, you will need to re-run sam build for the changes to be picked up.
You only need to restart SAM CLI if you update your AWS SAM template

I have the same issue. I get the error even with an empty handler.

Using version SAM CLI, version 1.131.0.

@sumit-popclub did you manage to fix it?
