Failed to send Qianwen prompt

Error message

Failed to send Qianwen prompt

What it means

CommandExecutionError thrown when sendMessage fails to submit the prompt to the Qianwen chat UI (send.ok falsy), carrying sendMessage's reason as the message. If a login gate is detected instead, an AuthRequiredError is thrown rather than this error.

Solutions

1. Read the send.reason embedded in the error to identify the exact DOM failure.
2. Re-login if a login gate appeared, then retry.
3. Retry after increasing pre-send wait times; refresh the page so the composer is fully hydrated.
4. Update the library if the Qianwen UI selectors changed (check for a newer version).

Example fix

// before
const out = await qwenAsk(page, { prompt: 'hi' });
// after
try {
  const out = await qwenAsk(page, { prompt: 'hi' });
} catch (e) {
  if (e instanceof CommandExecutionError) {
    await page.reload();
    await page.wait(5);
    // retry once
  } else throw e;
}

// ensure page is settled before sending
await page.wait(3);
if (await hasLoginGate(page)) { await qwenLogin(page); }

function isSendFailure(e) {
  return e instanceof CommandExecutionError && !/No assistant reply|timeout/i.test(e.message);
}

try {
  await qwenAsk(page, { prompt });
} catch (e) {
  if (e instanceof AuthRequiredError) { await qwenLogin(page); }
  else if (isSendFailure(e)) {
    await page.reload(); await page.wait(5);
    await qwenAsk(page, { prompt }); // single retry
  } else { throw e; }
}

When it happens

Trigger: sendMessage returns {ok:false} because the composer/submit button could not be found or clicked, the textarea was not editable, or the page state was unexpected; reason string propagates into this error.

Common situations: Qianwen UI markup changed after a frontend deploy; page still loading when send was attempted; modal/overlay (login, rate-limit, maintenance banner) intercepting clicks; session logged out mid-flow.
