Hello Google Support Team,
I am experiencing persistent HTTP 500 Internal Server Errors while using Antigravity. The application is failing to process requests and returning an “Internal error encountered” message.
Key Details About the Behavior:
Duration: I have been experiencing this issue consistently for the past two days.
Scope: The error is not isolated to one specific model; it occurs regardless of which model I select.
Timing: The 500 error is returned instantly the moment I submit a prompt or request. It does not hang or load, suggesting the failure happens immediately upon hitting the server, before the model even attempts to process it.
Troubleshooting Attempted: I have completely logged out and back in, and fully uninstalled/reinstalled the Antigravity app to clear any corrupted local tokens. The issue persists, confirming this is a backend issue.
Since the error is a 500 status code, this appears to be a server-side routing or authentication issue on the backend rather than a local configuration problem.
Account & Subscription Context (Potential Root Cause):
Please note that I recently changed my primary account email from @gmail.com to @binarybites.dev. I have a Google Workspace AI Ultra subscription attached to my account. Because these instant 500 errors started right around the time of the email change, I suspect there may be a token, licensing, or authentication mismatch on the backend preventing the API from recognizing my AI Ultra access under the new .dev domain.
Below are the exact diagnostic logs, headers, and Trace IDs from the most recent crash to help your engineering team investigate:

Account: @binarybites.dev (formerly @gmail.com)
Steps to Reproduce:
Open the Antigravity application.
Ensure the application is signed in using the account info@binarybites.dev (which holds the AI Ultra license).
Select any available AI model from the interface.
Type a standard prompt or code generation request into the chat/input box.
Hit send/submit.
Result: The request fails instantly without loading. The UI returns an “Internal error encountered” message, and the backend logs show an HTTP 500 status code with the trace IDs provided above.
Thank you
