Project ID discovery failed - set ANTIGRAVITY_PROJECT_ID in

Error message

Project ID discovery failed - set ANTIGRAVITY_PROJECT_ID in environment.

What it means

Authentication is valid, but the project-discovery API call returned no project: _fetch_project_id came back empty/None. The account's token works, yet no eligible Google Cloud project for Antigravity could be found via the API. The message tells you the escape hatch: set ANTIGRAVITY_PROJECT_ID.

Solutions

1. Set ANTIGRAVITY_PROJECT_ID=<your-gcp-project-id> in the environment — deterministic fix.
2. Complete the onboarding/login flow fully so the Antigravity service registers a cloudaicompanion project for the account.
3. Verify in Google Cloud Console that the intended project exists and has the Code Assist API enabled.

Example fix

# before
export ANTIGRAVITY_PROJECT_ID=

# after
export ANTIGRAVITY_PROJECT_ID=my-gcp-project-id

project = (Antigravity.auth_manager.get_project_id()
           if Antigravity.auth_manager else None)
if not project:
    project = os.environ.get("ANTIGRAVITY_PROJECT_ID")
if not project:
    raise RuntimeError("no project: run login or export ANTIGRAVITY_PROJECT_ID")

try:
    await antigravity.create_async_generator(...)
except RuntimeError as e:
    if "Project ID discovery failed" in str(e):
        os.environ["ANTIGRAVITY_PROJECT_ID"] = known_project_id  # fallback
        raise  # or retry with pinned project

When it happens

Trigger: get_access_token() succeeds, but the Cloud Resource Manager / loadCodeAssist project lookup returns no usable project — e.g. the account belongs to no projects, all projects lack the required API, or onboarding was never completed so the service reports no cloudaicompanion project.

Common situations: New Google account with no GCP project created; project exists but Cloud AI Companion API disabled; onboarding step (error 106) was skipped or failed, so no project was associated.
