Scheduled notebooks failing

[tssau]

All scheduled daily notebooks on AGOL have been failing since 10/29/2025. Even with a newly created notebook that only does print('test').

Here is the result of the task:

{
  "error": {
    "code": 90031,
    "message": "Invalid value for executionTimeoutInMinutes for notebook job run.",
    "messageCode": "NBO_90031",
    "details": []
  }
}

 AGOL bug?

We've been having the same issue, this also started happening the 10th of October. 

Every time there's an AGOL update something seems to unexpectedly break.....

Same issue for us. Oct, 29 is when ours started failing too. AGOL updates these days now feel like 1 step forward and 2 steps back.

I am also having the same problem. Interestingly, one of our notebook tasks is still running successfully. The other notebooks that are failing as tasks are able to run manually.

Agreed.  same timeframe for our sudden "executionTimeoutInMinutes" Errors.   but as mentioned,  the Notebook scripts run manually without Error.

I updated a notebook the runtime to standard 12 yesterday, reactivated it, and it actually ran on its own this morning.
