No valid access token available for project discovery

Error message

No valid access token available for project discovery

What it means

While resolving the Google Cloud project for the request, the provider had no cached project ID (neither in-memory nor in the credentials file) and auth_manager.get_access_token() returned None, so the Cloud Resource Manager project-discovery API call cannot be made. It means authentication was never initialized or has fully expired with no refresh path.

Solutions

1. Run the interactive login flow first so a valid access token and project ID are cached.
2. Set ANTIGRAVITY_PROJECT_ID in the environment to skip discovery entirely — this is the fastest unblock.
3. Ensure initialize_auth() is awaited before making requests in custom code.

Example fix

# before: request fires before auth is ready
await Antigravity.create_async_generator(...)

# after: initialize auth (or login) first
await Antigravity.auth_manager.initialize_auth()
# or pin the project explicitly:
# export ANTIGRAVITY_PROJECT_ID=my-gcp-project

await Antigravity.auth_manager.initialize_auth()
assert Antigravity.auth_manager.get_access_token(), "run login first — no access token"
assert Antigravity.auth_manager.get_project_id() or os.environ.get("ANTIGRAVITY_PROJECT_ID"), "set ANTIGRAVITY_PROJECT_ID"

def auth_ready_for_discovery(auth_manager) -> bool:
    """True when a token exists so project discovery can proceed."""
    return bool(auth_manager.get_access_token()) or bool(auth_manager.get_project_id())

try:
    await antigravity.create_async_generator(...)
except RuntimeError as e:
    if "No valid access token" in str(e):
        await Antigravity.login()  # then retry once
        raise

When it happens

Trigger: Calling create_async_generator/get_quota before initialize_auth() completed, or after the token cache and refresh both failed, leaving get_access_token() == None while a project ID is still unknown.

Common situations: First use on a fresh machine without saved credentials; credentials file deleted; token refresh failing (see errors 100/101) before a project was ever cached.
