Could not find Antigravity input box

Error message

Could not find Antigravity input box

What it means

Companion error to 242 in the same bounding-box evaluate: the input container was found but it holds no [data-lexical-editor="true"] element, so the editor rect for the mouse-click coordinates cannot be computed.

Solutions

1. Wait for the editor selector inside the container before computing the rect
2. Retake/reopen the panel to force editor mount
3. Update selectors to match current Antigravity markup (including shadow DOM/iframe traversal if needed)
4. Retry with backoff to let React/Lexical hydrate

Example fix

// before
const editor = container.querySelector('[data-lexical-editor="true"]');
if (!editor) throw new Error('Could not find Antigravity input box');
// after
const editor = await page.waitForSelector('#antigravity.agentSidePanelInputBox [data-lexical-editor="true"]', { timeout: 10000 });
if (!editor) throw new Error('Could not find Antigravity input box');

const editorExists = await page.evaluate(() =>
  !!document.querySelector('#antigravity.agentSidePanelInputBox [data-lexical-editor="true"]'));
if (!editorExists) throw new Error('Lexical editor not mounted inside input container');

function hasEditorRect(el) {
  const editor = el?.querySelector?.('[data-lexical-editor="true"]');
  return editor instanceof Element && editor.getBoundingClientRect().width > 0;
}

try {
  await sendMessage(message);
} catch (err) {
  if (err.message.includes('Could not find Antigravity input box')) {
    await sleep(1000); // allow React/Lexical hydration
    await sendMessage(message);
  } else throw err;
}

When it happens

Trigger: Rect-extraction evaluate finds the container, then querySelector('[data-lexical-editor="true"]') returns null.

Common situations: Panel rendered a placeholder/skeleton without the editor yet; Antigravity switched away from Lexical in an update; editor is inside a shadow root or iframe that querySelector can't reach.
