Not working when using module in Python

Bug Report

Current Behavior

When running sls offline and accessing the url I have the following error:

Traceback (most recent call last):
  File "/[src]/node_modules/serverless-offline/dist/lambda/handler-runner/python-runner/invoke.py", line 76, in <module>

    module = import_module(args.handler_path.replace(os.sep, '.'))
  File "/opt/miniconda3/lib/python3.9/importlib/__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "<frozen importlib._bootstrap>", line 1030, in _gcd_import
  File "<frozen importlib._bootstrap>", line 1007, in _find_and_load
  File "<frozen importlib._bootstrap>", line 984, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'handler'

Sample Code

• file: serverless.yml

service: my-service

plugins:
  - serverless-offline

provider:
  runtime: python3.9
  stage: dev

functions:
  hello:
    handler: handler.hello
    module: my_module
    timeout: 30
    events:
      - http:
          path: /hello
          method: get
          cors: true

• file: my_module/handler.py

def handler(*args):
    print('hello')

Expected behavior/code

Should work just line when not using the module in serverless

Environment

• serverless version: 2.66.2
• serverless-offline version: 8.8.0
• node.js version: 12.22.6
• OS: MacOs 12.4

Your Environment Information ---------------------------
     Operating System:          darwin
     Node Version:              12.22.6
     Framework Version:         2.66.2
     Plugin Version:            5.5.1
     SDK Version:               4.3.0
     Components Version:        3.18.1

optional, if you are using any of the following frameworks to invoke handlers

• python version: 3.9

Possible Solution

I'm guessing when trying to find handler it should take into account the module if specified but it currently doesn't?

Additional context/Screenshots

[mebibou]

Note: it might be the same kind of error as #1381, but I am using a module while that other issue is not but using deep handler, so the resolution might be different

[dnalborczyk]

#1381 was reverted in v8.8.0, if you are sure that you are using that version your issue should be a different one.

if you could digg into this problem and put up a PR that would be great. if not, a repro would be very helpful as well.

@dnalborczyk ok created a PR based on what I modified locally to make it work. Not sure if it should be that simple, but it works

I'm closing this @mebibou I hope that's ok, as this is not a supported config feature by serverless itself. #1467
