BUG: Persistent HTTP 500 Internal Server Error consuming credits in Antigravity

Corpo da mensagem (Copie tudo abaixo desta linha):

Hello team,

I am experiencing a persistent issue in the Antigravity IDE where the agent execution constantly terminates due to an HTTP 500 Internal Server Error.

This is happening across multiple different models, including Gemini Pro and Claude Opus, which indicates a backend/infrastructure failure rather than a prompt or model-specific issue.

Critical Issue: Even though the server fails to return a response and throws a 500 error, my credits are still being consumed/deducted for these failed requests.

Here are the debug logs with the Trace IDs for investigation:

Error Details:

  • Error: HTTP 500 Internal Server Error

  • TraceID 2 (from previous log): 0xea0b1dd9025d1…

{ “error”: { “code”: 500, “message”: “Internal error encountered.”, “status”: “INTERNAL” } }

Could you please investigate the server-side failure using these Trace IDs and refund the credits that were incorrectly consumed by these server crashes?

Thank you.

Antigravity become unusable, rather than giving the task to one of the model, we stayed retrying every prompt 10s of times to get single response !!
the problem i am Pro user, and if everyone are suffering from these issues i don’t see any logical reason to upgrade to Ultra anymore.

this my common error with 3.1 Pro (high)

I have this problem too.
