I’m following this tuto Build an AI voice assistant with Rasa Open Source and Mozilla tools | Rasa

Ok, thanks a lot for both of you
Any solution yet? I’m stuck on the same type of error (but for a custom telegram implementation) where it just says “RasaException: Failed to find input channel class for 'custom.telegram2”
