Hi,
I’m using Docker with images:
Start command
run -m models --enable-api --cors "*" --debug
Issue
The header Access-Control-Allow-Origin seems to be missing for socket.io:
I think this issue may be similar to this one: RASA Core: –cors parameter does not apply to socket.io
I’ve tried the suggestions with no results so far.
Did I miss something?
I am currently working on a project with @caubin and we get a CORS error when trying to connect the WebChat widget to Rasa… Like explained above !
Do you have any suggestions to make it work ?
Thank you for your time ^^
From Google Chrome console:
Access to XMLHttpRequest at ‘https://domain.com/socket.io/?EIO=3&transport=polling&t=N2h2Iyj’ from origin ‘null’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
webchat-latest.js:48 GET https://domain.com/socket.io/EIO=3&transport=polling&t=N2h2Iyj net::ERR_FAILED
Thanks,
Kind regards
Can you show the error messages in the rasa logs? And what command are you using to run it?
@akelad Im working with @Abdessamad on this project. Im trying to deploy the rasa docker image into our Azure plateform.
We are running rasa with the command: run -m models --enable-api --cors "*" --debug
To clarify, when calling rasa with Webchat on local system (http://localhost:5005/) we have a null header:
Access-Control-Allow-Origin: null
When calling to Azure deployed rasa (https://azure.domain/) we have no Access-Control-Allow-Origin header and the error:
Access to XMLHttpRequest at 'https://azure.domain/socket.io/?EIO=3&transport=polling&t=N2h2Iyj' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
webchat-latest.js:48 GET https://azure.domain/socket.io/?EIO=3&transport=polling&t=N2h2Iyj net::ERR_FAILED
From rasa logs:

Im guessing that in order to make it work on Azure we should have Access-Control-Allow-Origin: * when calling rasa on local.
@caubin do you see a debug message about CORS near the top of the logs?

@erohmensing We don’t have the mention of CORS configuration in our logs and a far as I remember we never had one.
Log looks like this:

Also share with us your endpoint.yml file
index.html (1.2 KB) endpoints.yml (1.4 KB)
Im working with @Abdessamad, you can find the 2 files requested in attachment.
Please @caubin add this at the end of your endpoints.yml file
socketio:
user_message_evt: user_uttered
bot_message_evt: bot_uttered
session_persistence: true@wabi We have this part in our credentials.yml file, which is the correct one?
Rasa log with socketio conf in endpoints.yml:

FYI we have in our credentials.yml file:

rasa:

hey @caubin, just start the rasa server using this command:
rasa run -m models --enable-api --cors “*” --debug
Please read the discussion before 
That is exactly the command we are using to run Rasa !
