Streaming Function hard-terminated at exactly 30s instead of documented 60s

My Netlify Streaming Function is being hard-terminated at exactly 30,000 ms.

Site: y-ielts-staging

Site ID: 25ed46b8-925d-4b73-9cdc-3faf9895b401

The Function returns a ReadableStream. The upstream AI provider succeeds and streaming begins normally, but the Netlify invocation is terminated at exactly:

Duration: 30000 ms

Example invocation ID:
db303694

Before termination:

  • provider request succeeds
  • HTTP 200 streaming response is established
  • stream remains active
  • there is no provider timeout
  • there is no application error
  • there is no client cancellation

There is also no repository configuration setting a 30-second Function timeout.

Current Netlify documentation states a 60-second execution limit for synchronous/streaming Functions.

Could a Netlify team member please check whether this site or account has a legacy 30-second Functions timeout/profile and update it to the current 60-second limit?
