**Description:** I am encountering a persistent error when using Antigravity. Even after re-logging and clearing cache, the issue remains. It appears that the backend is failing to assign a valid Project ID, returning “projects/” instead. **Error Details:** - **Error Message:** Invalid project resource name projects/ - **Status:** INVALID\_ARGUMENT (HTTP 400) - **TraceID:** 0x67d6db80ab4… - **Trajectory ID:** 14c5d787-5ddd-4cbd-bf9c-c19bee… **Troubleshooting performed:** - Cleared local configuration and cache. - Re-authenticated with Google Account. - Revoked and re-granted App permissions. This seems to be a widespread backend synchronization issue. Please investigate why my account is not being assigned a valid project resource name. ---

The same, reported twice, by last 2 weeks, with Report Issue from Antigravity…. nothing changed after 1.20.5 from Mar 9, 2026, the same problem. Logout, removing Antigravity from [accounts.google.com](http://accounts.google.com), reauth… still the same problem. Google AI Pro account. For sure those 400 are visible in logs, and one can assume that if you are building tool for using AI to code, you probably should use it also to look into logs 😉 Two separated traceId’s: Trajectory ID: 0240dcd9-3959-40dd-867c-5e7b85… Error: HTTP 400 Bad Request Sherlog: TraceID: 0x7c24946c774..

Same here with a fresh installation on a new macbook pro (M5 pro). Workspace and playgrounds are not working every chat is directly stopping with the same error / bug like this: Trajectory ID: 4b6acd45-bae2-46da Error: HTTP 400 Bad Request Sherlog: TraceID: 0xd62e46d type: “[type.googleapis.com/google.rpc.BadRequest](http://type.googleapis.com/google.rpc.BadRequest)” description": “Invalid project resource name” field": „name" message: "Invalid project resource name projects/„ status: “INVALID\_ARGUMENT” I’ve already send a bugreport directly from antigravity too ---

Next update, and still the same problem which I have last ~5-6 weeks 😉 Invalid project resource name… time to switch to Kiro, and maybe canceling Google AI Pro, why to pay extra if I cannot use it with Anitgravity? ---

Don’t know if it will help anybody but you can try. I had this problem by last ~2 months. I even have ticket to Google One. By total coincidence today I clicked on .md file (Markdown) and it was opened in Antigravity. So I put “Are you there?” to chat and it responded… So I reopened my project with 400… and 400 was there again… So I copied all visible files from this folder to new one, went there and done: `antigravity .` and it worked, and there is no 400… So my guess is that at least in some cases this is problem somewhere in your local file system. Try to copy files (source code, docs, data files, but nothing more) to new folder and run antigravity there. It may help. It helped in my case - at least for now 😉 ---

even better, now even project which was throwing 400 works 😉 so it seems that folks in Google fixed problem on theirs side 😉
