antigravity cookies: document.cookie is empty.

Error message

antigravity cookies: document.cookie is empty.

What it means

The cookies command reads document.cookie on the Antigravity renderer via CDP and throws EmptyResultError when it comes back falsy. document.cookie only exposes non-HttpOnly cookies for the current origin, so an empty result usually means all cookies are HttpOnly or none were set for that page yet.

Solutions

1. Interact with the app (sign in / load a workspace) so cookies get set, then re-run.
2. Use CDP Network.getAllCookies via a DevTools script to see HttpOnly cookies too.
3. Check localStorage/sessionStorage instead: `opencli antigravity storage-keys` — tokens often live there.
4. Verify the attached page URL origin matches the origin that sets the cookies.

Example fix

// before (expecting tokens in document.cookie)
opencli antigravity cookies
// after
opencli antigravity storage-keys --filter auth

// Only expect document.cookie data after the app has loaded/authenticated
const authed = execSync('opencli antigravity storage-keys --filter auth', {encoding:'utf8'});
if (!authed.trim() || /is empty|No keys/.test(authed)) console.warn('renderer appears unauthenticated; cookies likely empty too');

function looksAuthenticated(storageKeysOutput) {
  return typeof storageKeysOutput === 'string' && /auth|token|session/i.test(storageKeysOutput);
}

try {
  run('opencli antigravity cookies');
} catch (e) {
  if (/document\.cookie is empty/.test(e.message)) {
    console.warn('No JS-visible cookies (all HttpOnly or none set); falling back to storage inspection');
    run('opencli antigravity storage-keys');
  } else throw e;
}

When it happens

Trigger: Running `opencli antigravity cookies` before the renderer has performed any authenticated request that sets a JS-visible cookie, or when every cookie is HttpOnly (invisible to document.cookie), or on a blank/about page with no cookie scope.

Common situations: Trying to inspect auth/session tokens that Antigravity stores in HttpOnly cookies or in the keychain instead of document.cookie; attaching the CDP session to a fresh window that has not navigated to the app origin.
