KeyError when deploying Python Function App on Azure

Question

I'm new to azure and I'm getting this KeyError when deploying my python function on Azure portal, not sure what is the reason.

I have added just one package, "tweepy == 3.8.0" in my requirements.txt and it seems like it is crashing mostly right during it's installation during deployment, And the PySocks package is probably just a dependency for tweepy package.

I have no such issues when the debug it locally. The function runs absolutely fine locally.

How can I resolve this deployment issue?

Error:

There was an error restoring dependencies. Traceback (most recent call last):

"func: pack" task has been a common problem for users. I could solve it by trying a preview feature that is meant to address this: https://github.com/microsoft/vscode-azurefunctions/wiki/Server-Side-Build
