Antigravity 1.20.6 on macOS fails with "Invalid project resource name projects/" after sign-in

Hi team,

I’m seeing a reproducible failure in Antigravity 1.20.6 on macOS.

Environment:

- Antigravity version: 1.20.6

- macOS: Apple Silicon Mac

- Reproduces in a fresh project folder

Problem:

Agent requests fail with HTTP 400 and the backend returns:

Error: HTTP 400 Bad Request

TraceID: 0x7a8710dadce0310b

{

“error”: {

“code”: 400,

“details”: [

{

“@type”: “type.googleapis.com/google.rpc.BadRequest”,

“fieldViolations”: [

{

“description”: “Invalid project resource name”,

“field”: “name”

}

]

}

],

“message”: “Invalid project resource name projects/”,

“status”: “INVALID_ARGUMENT”

}

}

What I already tried:

- Cleared local app state and cache

- Re-signed in

- Opened a fresh test project folder

- Started a brand new chat instead of retrying an old one

Additional note:

Before this, the app was also hitting a separate local crash:

`TypeError: Do not know how to serialize a BigInt`

That local issue was worked around, but agent requests still fail with the project resource error above.

Expected:

Antigravity should resolve or attach a valid project resource automatically after sign-in and when opening a project folder.

Actual:

Requests are sent with an empty project resource like:

`projects/`

This looks like project/account context is not being initialized correctly.

Let me know if you want more debug info.

Hi @chaichai
Welcome to the Google AI Forum!!!

When the primary email identity changes, the automated linking breaks resulting in an Invalid project resource name projects/ error, try:

  • Find your original email in the Alternate emails section of your Google Account settings
  • Click make this your google account email
  • Re-login to Antigravity

This might help resolve the issue.
