Gemini Deep Research Agent interaction deleted results

25 days ago (Jan 5th) I used the Interactions API to run a Deep Research Agent, which completed and returned the result. Now, I’m trying to acces the output again, but it seems to have been lost, with the status stuck in “in_progress” and output in null. This was 25 days ago and using a paid API key, so the results should still be stored, as it has been less than 55 days. The API requests return 200 on my end, but on AI Studio I see 503s.

Output:

Interaction(
id=‘v1_ChdRRzViYWNMMUROamluc0VQdGJPNTZRZxIXUUc1YmFjTDFETmppbnNFUHRiTzU2UWc’,
status=‘in_progress’,
agent=‘deep-research-pro-preview-12-2025’,
created=datetime.datetime(2026, 1, 5, 7, 54, 40, tzinfo=TzInfo(0)),
model=None,
object=‘interaction’,
outputs=None,
previous_interaction_id=None,
role=‘agent’,
updated=datetime.datetime(2026, 1, 5, 7, 54, 40, tzinfo=TzInfo(0)),
usage=None
)

(neither the prompt nor the original response contain any sensitive or private information)

Many other Deep Research Agent interactions also from Jan 5th have the same problem.
