Antigravity Invalid project resource name projects/ error

I am getting this error every time I run Antigravity.

Error:
Invalid project resource name projects/

What I already did:

  • Created a new GCP project
  • Enabled Generative Language API
  • Added Project ID in Antigravity settings
  • Restarted Antigravity

Still the error continues.

Is this a bug or am I missing something?

Serioulsy, dont hate me for saying this, BUTTT have you tried updating to the latest version. Its sounds dumb but thats a similiar error that i had until I updated it, by going into the settings. i didnt get a update to latest version notification which is why i was tripping out

Thanks. I checked my version and I am already on Antigravity 1.20.6, but I still get the same “Invalid project resource name projects/” error on macOS.
