Answer 1

Ran into same issue, i solved it by using the plugin serverless-python-requirements for serverless framework and passing:

pythonRequirements:
    dockerizePip: true

Essentially this installs your c-based packages (and all other packages) in a docker container where it would work and then symlinks them to your lambda fn.

A helpful guide can be found on: https://serverless.com/blog/serverless-python-packaging/

Answer 2

The python client for Firestore relies on the C-based implementation of GRPC. This appears not to work by default in AWS Lambda.

Node.js users have reported similar problems and they've documented a workaround of building a docker image.

This should be similar to any getting any other python package that requires native code to work. Perhaps something like this method for getting scikit to work?

I hope this is enough to get you going in the right direction, but unfortunately I don't know anything about AWS Lambda :-(.
