Module initialization error

Question

I am using virtualenv and serverless-python-requirements for my Python deployment in AWS Lambda using the serverless framework. But after upload when I am calling the function it is giving “module initialization error: [Errno 22] Invalid argument” error.

I am new to the serverless framework so couldn't find out what I am doing wrong.

Here is my serverless.yml file https://gist.github.com/himadriganguly/f9571c09a3c01c79ebf920034f5e5e55

@tkwargs Edited my post and added the serverless.yml file link. Thank you. — Himadri Ganguly
I ran into something similar when trying with python 3.6 runtime. I ended up switching to 2.7 and everything worked fine. Check the docs on using Python 3.6. Also (in case you haven't already), verify you're in a virtualenv running Python 3.6 when deploying. Let us know if that helps! — maafk
Do think that there is any issue with Python 3.6 on AWS Lambda as before using serverless when I am packaging it manually to create a zip file and uploading it to Lambda it is working fine. — Himadri Ganguly

Error is fixed now, it is the serverless framework issue.

They have fixed it on 1.21.1 release.
