Am trying to check Rasa3 for our use along with the front end of rasa chat widget given in the Rasa docs, it gives socketIO error as follows, pls help me.
The WebSocket transport is not available, you must install a WebSocket server that is compatible with your async mode to enable it. See the documentation for details. (further occurrences of this error will be logged with level INFO)

Thanks @nik202. Am using Windows 10 PC for rasa server and the rasa web chat also in the same PC. Now the earlier is not occuring, but the following issue is showing both using MS Edge and Chrome.
The client is using an unsupported version of the Socket.IO or Engine.IO protocols (further occurrences of this error will be logged with level INFO)

hi @nik202 I was also not able to get responses from webchat to rasa, its just showing socket.io not found.
Below are the version of socketio, engineio and rasa
These are the versions and I tried with rasa-webchat by botfront and rasa-widget mentioned on docs.
I think this is the same issue like 2.3.x and 2.4.x had. Let me know if you have other thoughts
When we change these version, there are few fallbacks,
Sanic will give timeout errors when you use forms and have customized them.
We can’t use Entity Extractors properly since they too use async so giving timeout errors.
I did tried them so I reported here. Please let me know if you find something.
Rasa version:
Rasa Version : 3.0.0

Great @RajithaBandara can you share the rasa --version and socketIO related packages with the version please, whenever you get some time. Many thanks in advance.
Hi @nik202! Seems like I’ve got a similar issue, but struggling to get past it. I tried your instruction above install those 3 pip things, but still no websocket working.
When I send test msg on postman, I get this response: “The client is using an unsupported version of the Socket.IO or Engine.IO protocols”
When I run rasa --version
I get this read out in vscode:

Do you know where I’m going wrong?
Also, I am running my rasa server, via docker. So my container setup was done like this:
docker run -it -p 8080:8080 -v ${pwd}:/app rasa/rasa:latest-full run --enable-api --port 8080 --cors=“*”
@hgoona Well it’s an issue of Rasa bot front issue not an issue with Rasa itself. If you have explored the forum. I have already provided the solutions which best solve this issue. You need to try the versions.
thanks for the update.
can you share the rasa --version and socketIO related packages with the version please, whenever you get some time. Many thanks in advance.
