Working perfectly at 1159pm on July 30, exactly 1200 on July 31 this started mid run with no script changes.. Calls are hitting my Anitgravity quota on aistudio

  • What Happened:
    When client.interactions.create(agent="antigravity-preview-05-2026", environment="remote") made a request to Google’s remote agent server, the server returned an HTTP 403 Forbidden status with "The caller does not have permission".

Hi @Drew_Burch,

I tried to reproduce this on my end, but I wasn’t able to observe the same unexpected behavior. To help us investigate this further, could you please provide a bit more information?

  • Which version of Antigravity are you using?
  • Which operating system are you using?
  • Is there a specific model or sample prompt that is triggering this issue?

It is possible that this was a transient issue. However, if you continue to experience this, we recommend submitting a report using the in-product menu. Just navigate to Having trouble? Let us know > Provide feedback. Please ensure the “Attach Antigravity server log” box is checked, as this will greatly help us investigate the issue further.

Thank you for the response. I let the system sit for about 36 hours and it resolved itself. I am using antygravity in terminal via python3, M$ running Tahoe, I was using my prompt. I eventually resorted to using the demo script in the FAQ on aistudio. Same issue.. let it sit for a day or so and it work.. odd thing, when it did finally go, the tiny prompt on the FAQ sent 1.16M tokens.. maybe a buffer issue.. either way it is working now.. Thank you for your time.
