When I try rasa run from the bot dirctory, i got the following error:

@maraal did you manage to set it up?? im having the same issue

[aandrewsv]

Found the reason, was because i was not installing heyoo which is what the connector is using to send whatsapp messages so when rasa loaded the connector it was raising an ImportError.

If this hasn't solved the problem, you must import input class from the whatsapp.py to rasa/core/channels/init.py

Could you provide steps to do this, I also getting the same error

[aandrewsv]

You need to have heyoo installed in the python enviroment first so:

pip install heyoo

Then i've added whatsapp.py file at this route:

addons/whatsapp.py

Then in credentials.yml file i have this:

addons.whatsapp.WhatsAppInput:
  auth_token: "auth_token"
  phone_number_id: "phone_number_id"
  verify_token: "verify_token"

@aandrewsv Thanks , I got it working, It was an SSL issue. I moved the whatsapp.py to rasa/core/channels and modified rasa/core/channels/init.py to include whatsapp.
