Rasa-webchat with Rasa 2.7 and rasa_sdk 2.7

Rasa Open Source
1

Hello Everyone, Quick question. Has anyone gotten Rasa 2.7 and rasa_sdk 2.7 to work with rasa-webchat? I keep getting the Client socketio error when I startup Rasa with the following command: rasa run -m models --enable-api --cors “*”

My installation is strait up with no modifications. And the webchat works from Rasa 2.3 and rasa_sdk 2.3.1 on down but not beyond that version. Again, has anyone successfully gotten 2.7 to work with rasa-webchat. Not looking for a hack. Hoping there’s a straight forward solution that I have missed, after days of searching.

Thanks

Hi @eaofcc ,

I’m not quite sure, but I’d recommend to first check the socket-io compatibility table and to countercheck every tool used (Rasa OSS, SDK, …) if everything fits together.

Kind regards

Thanks! I actually did just that. So Rasa 2.7 has python-socketio 4.4, because of some issues with socketio compatibility. Not sure how to confirm the version that rasa-webchat is running. If I knew that, and how to change it if it’s not javascript socketio 3.x or 4.x, I’d be able to potentially solve the issue.

Best, Ethan Anthony

Hi @eaofcc ,

looking at this:

    "socket.io-client": "^3.1.2",
    "sockjs-client": "^1.4.0"
  },

This seems to be actually the problem! Can’t you simply clone the chat and run: npm update socket.io-client and the io likewise?

Kind regards

That’s a great idea. So I cloned the package and ran npm update. The result was tons of errors and difficult to resolve conflicts.

@eaofcc you just want to render your chatbot to rasawebchat(botfront) so that you can see the chatbot widget? Right

Yes. That’s it. While using Rasa 2.7 and rasa_sdk 2.7

@eaofcc Please try to change from 1.0.0 to 1.01

 (e.src =
>     "https://cdn.jsdelivr.net/npm/rasa-webchat@1.0.1/lib/index.js"),

Version 1.0.1 of the rasa webchat is made to work with version 2.3.x and 2.4.x of rasa and beyond. Use 1.0.0 for other rasa versions.

:warning: We recommend adding a version tag to prevent breaking changes from major versions, e.g for version 1.0.0 https://cdn.jsdelivr.net/npm/rasa-webchat@1.0.0/lib/index.js, however this will not work with versions below 1.0.0. If you do not specify a version, you will get served the latest available version of the rasa-webchat.

Please ref: GitHub - botfront/rasa-webchat: A feature-rich chat widget for Rasa and Botfront

This works PERFECTLY! Everyone should know this. I spent so much time struggling with this issue. 1.0.0 is for anything below version 2.3. THANKS!
