"name" attribute must have a value

Error message

"name" attribute must have a value

What it means

Frame.InnerText() (frame.go:1330) wraps the innerText action failure with 'getting inner text of %q'. The action waits for a selector match in the attached state within Timeout and then evaluates element.innerText. Failures wrapped here are element/selector timeouts, strict-mode violations, detached frames or destroyed execution contexts during evaluation, and page-side exceptions (e.g., overridden innerText getters throwing).

Solutions

1. Wait for the element (and ideally its text) before reading: await page.waitForSelector(sel, { timeout: 10000 }) or use locator(sel).waitFor().
2. Use resilient, unique selectors (data-testid) so rerenders don't invalidate them.
3. Call InnerText on the frame that actually owns the element.
4. Give slow apps more time: page.innerText(sel, { timeout: 60000 }).

Example fix

// before
const txt = await page.innerText('.alert');

// after
const alert = page.locator('.alert');
await alert.waitFor({ state: 'visible', timeout: 10000 });
const txt = await alert.innerText();

const el = page.locator('.alert');
await el.waitFor({ state: 'visible', timeout: 5000 });

try {
  return await page.innerText(sel, { timeout: 10000 });
} catch (e) {
  if (String(e).startsWith('getting inner text')) return null; // not rendered yet
  throw e;
}

When it happens

Trigger: No element matches before opts.Timeout; multiple matches with Strict:true; navigation/detach between resolution and evaluation; page scripts throwing from a patched innerText getter.

Common situations: Reading text of elements populated after async fetches; asserting toast/confirmation text that disappears quickly; querying elements on the wrong frame; React re-renders swapping the node between resolution and read.
