How to reference handlers in sub-directories in serverless-offline?

Windows 10 64bits

Node v12.16.3

Serverless 1.71.3

serverless-offline 6.1.7

DIRECTORY:

root:
- package.json
- /sub
-- __init__.py
-- sub_handler.py
- ...
- handler.py
- serverless.yml

Hi, I'm currently trying to test locally two lambda functions using serverless-offline. It's working for the handler in the root directory but it seems that serverless-offline can't reference other handlers in sub-directories..

How can I reference handlers in a sub-directory?

PS: This configuration works when deployed to AWS LAMBDA. I can post both paths.

Error when I try to post hello2:

[offline] Loading handler... (C:\Users\my_user\Desktop\serverless-offline\sub\sub_handler) Traceback (most recent call last):

Recently, I was getting the same problem, I updated the version of serverless-offline plugin and worked out for me
