Failed to find input channel class for 'connectors.custom_connector.CrispInput'

RasaException: Failed to find input channel class for 'connectors.custom_connector.CrispInput'. Unknown input channel. Check your credentials configuration to make sure the mentioned channel is not misspelled. If you are creating your own channel, make sure it is a proper name of a class in a module.

I have this docker-compose

      - ./addons:/app/connectors

    command:

      - run

  app:

    image: chatbot/actions

    expose: [5055]

dockerfile:

# Extend the official Rasa SDK image
FROM rasa/rasa-sdk:latest

ENV PYTHONPATH=/app:$PYTHONPATH
# Change back to root user to install dependencies
USER root

# To install packages from PyPI
RUN pip install --no-cache-dir crisp_api

# Use subdirectory as working directory
WORKDIR /app

# Copy any additional custom requirements, if necessary (uncomment next line)
COPY actions/requirements-actions.txt ./

# Change back to root user to install dependencies
USER root

# Install extra requirements for actions code, if necessary (uncomment next line)
RUN pip install -r requirements-actions.txt

# Copy actions folder to working directory
COPY ./actions /app/actions

# By best practices, don't run the code with root user
USER 1001

my credentials.yml:

rest:

connectors.custom_connector.CrispInput:
  identifier: 'xxxxxxx
