Google AI Studio Build Agent repeatedly fails with “Agent execution terminated due to error”

[Who_Me]

I am using Google AI Studio Build with Gemini 3.8 Flash. The Build Agent starts working, but after some time it repeatedly shows:

“Encountered retryable error from model provider: Agent execution terminated due to error.”

The task cannot be completed even after retrying.

Please investigate whether this is a model, agent, session, quota, or backend iss

ue.

Hello @Who_Me ,

Could you share a few more details so we can narrow this down?

1. Are you seeing this in your other apps as well, or only in this one?
2. Which prompt were you running when the error appeared?
3. Are you on the free tier, or do you have a paid plan?
4. Your applet ID would also help us look at your specific case.
