Hi everyone,
I’m hitting a wall with a persistent HTTP 400 Bad Request error while using Gemini 3 Flash via Antigravity and Cockpit Tools. I have an active Google AI Pro subscription, but I can’t get the agent to work.
The Issue: The agent terminates immediately with: Agent execution terminated due to error. Looking at the Sherlog/Trace logs, the request is sending an incomplete resource path: “Invalid project resource name projects/”. It seems like my Project ID is simply not being passed through, leaving the string empty after the slash.
My Setup:
OS: Windows 10/11
Specs: i5-13400f | RTX 3060 12GB | 16GB RAM
Tools: Latest versions of Antigravity
Everything I’ve tried so far (zero help):
-
Signed out and back in multiple times.
-
Created brand new Google Cloud projects and manually selected them.
-
Wiped the local config folders in %APPDATA%\Antigravity.
-
Tested with a completely fresh Gmail account — the 400 error persists.
-
Disabled all proxies/VPNs and ensured 2FA is active.
It really feels like a backend provisioning glitch where my account isn’t correctly “linked” to a project ID on Google’s side.

СС:@moderator — could you please check my account status? I’m looking for a backend reset or any way to force-refresh my provisioning. I’m paying for Pro but haven’t been able to use it for days.
