Deep Research Agent is `in_progress` for >1h (potentially indefinitively)

Starting today (2026-03-31), Gemini API Deep Research requests appear to be stuck in_progress . I’ve tried the same prompt 3x and all have been in_progress for over an hour. As per the comment in a similar bug reported earlier this month, these requests also are not failing after 1 hour.

If it still “stuck”, it may be due to the agent still running. If it timeouts due to 60 min max limit, it should fail. Let me know if that’s NOT the case.

Two issues:

  1. Deep research requests aren’t being processed
  2. Failing status after 60m aren’t being triggered

I am getting no failure note and no api errors are being recorded in studio

Has the output schema changed?
