My suspicion is that the issue was caused by #1825 (comment) (which was required unfortunately, and a correct fix is currently blocked by nextjs/react capabilities).

The library downgrade issue is a side effect of introducing request headers, which required a change to the provider interfaces.

So unfortunately there is no solution, bc reverting would mean re-introducing the other bugs.

Does this mean that in the current latest version, we cannot use the createStreamableUI method to update UI within StreamUI? If so, is there any recommended workaround or alternative approach for updating the UI in real-time when using the latest version of the SDK in a production environment on Vercel Edge Runtime?

Not sure if it's the same cause, but experiencing the same symptoms.

However probably of note, I'm deploying via firebase-tools onto a Google cloud function.

I cannot use createStreamableUI or async generator functions to stream a tool response in a streamUI call after deploying. Things work perfectly fine with next dev. No error is reported in server logs.

This is still shown as valid in the docs https://sdk.vercel.ai/docs/ai-sdk-rsc/streaming-react-components

Also, downgrading ai package to 3.1.32 did not help for me.

update to [email protected] and do not use createStreamableUI in streamUItool, which will work fine with the issue.

use yield to update the UI component instead of createStreamableUI().update()
