Dear all,
I have explained the issue and solutions which I tried. Please let me know if I missed sharing any important information.
pip version:
Rasa version:
Credentials.yml :
rest:
# # you don't need to provide anything here - this channel doesn't
# # require any credentials
socketio:
user_message_evt: user_uttered
bot_message_evt: bot_uttered
session_persistence: false
# This entry is needed if you are using Rasa X. The entry represents credentials
# for the Rasa X "channel", i.e. Talk to your bot and Share with guest testers.
rasa:
url: "http://localhost:5002/api"
endpoints.yml :
action_endpoint:
url: "http://localhost:5055/webhook"
Note: I did not make any modifications to the config.yml file. Moreover, I saved the modified files and trained the model again.
After the setup, I used this command to run the rasa server:
rasa run -m models --enable-api --cors "*" --debug
It seems like Rasa connects to the socket io successfully, but it throws some exceptions as follows:

Sanic version:
Yes, I used this command to change the Sanic version to see if it solves the problem:
pip install sanic==21.6.0 --use-deprecated=legacy-resolver
This time it partially worked. Rasa can communicate through the connected socket endpoint. Here is the result:

2022-01-26 17:44:44 DEBUG rasa.core.channels.socketio - User lUqkgEYlmqLsMuH8AAAD connected to socketIO endpoint.
It seems like now the exception is thrown only if the user disconnects from the socket. But I completely want to get rid of any exception even if it connects to the socket io as expected.
Note: Iām trying to connect socket io to my custom chatbot UI (not webchat).
Thank you
EDIT: The same issue was highlighted on GitHub - Socket Channel not working in rasa 3.0.0 #10412.
