AWS Lambda Error: Unable to import module 'function_name': No module named 'module._module'

问题

Please see the screenshots in particular after reading.

I am deploying a python script on AWS Lambda which uses the package impyla which has a dependency on the package bitarray.

from impala.dbapi import connect

My python file is called authorize_ingress.py which has a function called handle_authorize_ingress(event, context) which are properly configured. See the screenshots below:

My function's file:

The handler in lambda specified:

handler

The handler in code itself:

and my zip file has everything in the root (and not nested within a directory):

The package bitarray is installed automatically by impyla:

bitarray

Every single time, I am met with this response:

As of now, I have tried to:

The package was generated with zip -r option.
The files are in the root of the zip and not nested within a directory.
The function works perfectly fine locally.
I have tried both virtualenv and simply installing the dependencies in a packages/ path but no luck

Any ideas what I might be doing wrong? I generated my deployment package following AWS' Lambda Deployment Guide. Any help would be appreciated, thank you!

Here you go. You can download this lambda layer through this gdrive link. This layer is compatible with Python 3.8, so make sure you select the correct lambda runtime.

If you are curious to know how I generated this lambda layer, here is a list of basically what I did:

Serverless Framework
serverless-python-requirements plugin
docker
serverless.yml

service: serverless-example

provider:
  name: aws
  runtime: python3.8
  region: us-east-1
  profile: dummy

functions:
  dummy:
    handler: dummy.handler

plugins:
  - serverless-python-requirements

custom:
  pythonRequirements:
    dockerizePip: non-linux
    layer: true
