Flowise Error: Expected content-type to be text/event-stream, Actual: application/json; charset=utf-8

[j-d-carmichael]

flowise: latest
embed code: suggested from flowise

I am having the exact same issue as https://stackoverflow.com/questions/79005072/flowise-error-expected-content-type-to-be-text-event-stream-actual-applicatio

• We have flowise protected behind and nginx proxy.
• Everything works fine except the embedded chatbots don't fully function... they load just fine, but it sends a request to know if it should stream or not.. it returns streaming: true.
• When sending the question to the server, streaming: true is sent in the payload but the response from the server, is application/json

This results in the embedded js code saying:
Flowise Error: Expected content-type to be text/event-stream, Actual: application/json; charset=utf-8

The same agent works fine within the "designer canvas", but we also note that in the flowise designer a socket connection is established where as with the embed code there is no socket established.

Any ideas?

Hey guys, I am the one who created the stackoverflow above. After researching for some hours I found out that the latest versions 2.0.1 and 2.0.0 are the ones not working, so in case your are copying and pasting the embedding script add the version 1.3.14

import Chatbot from "https://cdn.jsdelivr.net/npm/flowise-embed@1.3.14/dist/web.js

I didn't research further to understand why the latest versions are not working so in case someone knows the real issue please share it.

So its to do with the new SSE streaming not working with this new FlowiseEmbed version? Was hoping the day had come where we could finally see responses streamed!

Same here

Same problem here. The tip from @Panconjugo23 helped, many thanks!
I will put the working web.js on my own server to avoid surprises in future.

This is still not fixed.
I'm having the same problem on a wordpress website + nginx

Manually adding the version number as @Panconjugo23 mentioned is still the only solution.

Same here version 2.0.6 no likely

web.js:1 EventSource Error:  Error
    at onopen (web.js:1:931822)
    at A (web.js:1:923895)
    ```

Same here version 2.0.6 no likely

web.js:1 EventSource Error:  Error
    at onopen (web.js:1:931822)
    at A (web.js:1:923895)
    ```

UPDATE - I was running an old version of flowise on the backend so updating that has resolved my issue.

I found a fix for this: #274

FYI, version 2.0.1 doesn't seem to have this problem.
