How to fix Quota limits and OAuth issue in Antigravity?

by
You are hitting Quota limit or OAuth failures in the Antigravity extension even with a paid plan. Logs show the language server client is not ready when auth and status code run, so the token never binds and you appear logged out.

Antigravity quota or OAuth error triggered by language server init order

Symptoms match this startup sequence and errors: 
2026-01-24 21:46:36.769 [info] [Window] Started local extension host with pid 12873.
2026-01-24 21:46:37.365 [error] [Window] [Extension Host] Failed to update user status Error: LanguageServerClient must be initialized first!

Solution Overview

AspectDetail
Root CauseInit order bug: the extension calls auth and status code before the LanguageServerClient is ready, so the auth token never reaches the language server and you are treated as logged out.
Primary FixGate all auth and polling logic behind LanguageServerClient readiness, then set the token on the server and only then start status or model polling. Update to the patched build if available.
ComplexityEasy for end users, Medium for maintainers
Estimated Time5 to 15 minutes for users, 30 to 60 minutes for code fix

Fix the init order and rebind auth to the language server

Step-by-Step Solution

For end users: fast recovery without code changes 1. Reload the extension after sign in * Sign out inside Antigravity if signed in. * Reload the window with the VS Code command palette – Press Ctrl Shift P or Cmd Shift P – Run Developer Reload Window * Sign in again, then wait ten to twenty seconds for the language server to start before invoking any Antigravity commands. 2. Force token rebinding to the language server * Open the command palette – Run Antigravity Restart Language Server – Run Antigravity Reset Authentication * Wait for logs like: 
 [Extension Host] Authenticated session detected; setting auth token
 I0124 ... client.go:137] auth token set
 ```
 * If your build has a setting to defer startup logic, enable it, reload, then sign in:
 ```
 // settings.json
 {
 "antigravity.deferLanguageServerInit": true
 }
 ```
 After the language server reports ready, trigger Sign in from the Antigravity status bar.

3. Update to the latest Antigravity extension
 * Open Extensions view, update Antigravity.
 * Restart VS Code once after the update.

For maintainers: definitive code fix

Gate every feature that needs the LanguageServerClient behind onReady, then propagate the token, confirm acknowledgment, and only then start polling.

TypeScript example pattern:
ts // 1. Construct and start the language server client early in activate() const lsClient = new LanguageClient(“antigravity”, serverOptions, clientOptions); context.subscriptions.push(lsClient.start()); // 2. Wait until the client is actually ready await lsClient.onReady(); // 3. Fetch token from the existing auth session const session = await authProvider.getSession({ createIfNone: false }); if (session?.accessToken) { await lsClient.sendNotification(“antigravity/authToken”, { token: session.accessToken }); } // 4. Only now start loops that depend on auth or server state startUserStatusPolling(lsClient); startModelsRefresh(lsClient); 

Go server side token handler should be idempotent and confirm success:
go // client.go func (c *Client) SetAuthToken(tok string) error { if tok == “” { return fmt.Errorf(“empty token”) } c.token.Store(tok) klog.Info(“auth token set”) return nil } 

Also ensure user status refresh is gated on a present token:
go // log_context.go if c.Token() == “” { return fmt.Errorf(“not authenticated”) } “` Add a one time ready latch so no status update runs before onReady resolves. For additional patterns that prevent user side quota flares while auth is rebinding, see this follow up on quota thresholds.

Alternative Fixes and Workarounds

Best temporary workaround for users 1. Downgrade to the most recent stable version that does not exhibit the init order issue. 2. Disable background polling until a patched build is installed “` // settings.json { “antigravity.userStatus.enabled”: false, “antigravity.models.autoRefresh”: false } “` Re enable after updating. Next best 1. Delay activation * Do not trigger any Antigravity commands until you see Language server started in Output. * Then sign in and proceed. Last resort 1. Sign out, remove cached session with your OS keychain manager, restart VS Code, then sign in again. This forces a clean token path and increases the chance that the first token set lands after the language server is ready.

Troubleshooting Tips

  • Confirm the signature of the issue
– Look for both of these lines in your logs “` [Extension Host] Failed to update user status Error: LanguageServerClient must be initialized first! W… client.go:137] failed to set auth token “`
  • If auth still fails
– Check your system time. Large clock skew can break OAuth. – Corporate proxy or intercepting TLS can block token exchange. Try on a clean network.
  • After applying the fix
– You should see both of these lines within a few seconds of startup “` [Extension Host] Authenticated session detected; setting auth token I… client.go:137] auth token set “` For a broader explainer on how client behavior can resemble quota issues during auth faults, check this Antigravity quota writeup.

Best Practices

  • Always wait for the language server client ready event before calling any methods that depend on it.
  • Make token set idempotent and safe to retry.
  • Gate background loops like user status and models refresh on both server ready and token present.
  • Emit explicit logs for each stage ready, token propagated, polling started so operators can verify the sequence quickly.
  • Add an integration test that launches the extension, delays the server, and asserts no auth or polling attempts occur before onReady.

Final Thought

Fixing the init order so the client is ready before setting the token resolves the false logged out state and clears the Quota limit or OAuth failures. Apply the steps above and you should see healthy startup logs and normal model access within minutes.
