Unexpected Coupang probe: ${JSON.stringify(probe)}

Error message

Unexpected Coupang probe: ${JSON.stringify(probe)}

What it means

CommandExecutionError thrown by verifyCoupangIdentity when the in-page probe returns something that is neither {kind:'auth'} nor {ok:true} — e.g. null/undefined (evaluate returned nothing, page crashed, navigation failed) or an unexpected shape. Unlike the auth cases, this indicates an unexpected runtime state, not a clean 'not logged in' answer.

Solutions

1. Read the JSON.dumped probe in the message to see the actual value and diagnose from there
2. Retry verification — transient slowness is the most common cause
3. Increase the wait after page.goto('/np/mypage') (currently page.wait(3)) if mypage loads slowly
4. Verify evaluate snippet executes correctly in Chrome DevTools on mypage; fix escaping/marker mismatch if probe is null

Example fix

// before
 await page.goto('https://www.coupang.com/np/mypage');
 await page.wait(3);
// after
 await page.goto('https://www.coupang.com/np/mypage', { waitUntil: 'networkidle' });
 await page.wait(5);

// ensure mypage loaded before probing
await page.goto('https://www.coupang.com/np/mypage', { waitUntil: 'networkidle' });
if (!/mypage|쿠팡/.test(await page.evaluate(() => document.title))) {
  throw new Error('mypage did not load as expected');
}

function isOkProbe(probe) {
  return probe != null && typeof probe === 'object' && probe.ok === true && typeof probe.name === 'string' && probe.name.length > 0;
}

try {
  const identity = await coupangVerify(page);
} catch (err) {
  if (/Unexpected Coupang probe/.test(err.message)) {
    const raw = err.message.match(/Unexpected Coupang probe: (.*)$/)?.[1];
    console.warn(`probe=${raw} — retrying once`);
    await sleep(3000);
    return coupangVerify(page);
  }
  throw err;
}

When it happens

Trigger: page.evaluate returning null/undefined (navigation interrupted, page.goto failed silently, evaluate sandbox error); probe object with unexpected structure after Coupang markup/JS changes; the 3-second page.wait being insufficient so the probe ran against an intermediate page.

Common situations: Flaky network or slow mypage load; Coupang serving a challenge/interstitial page that returns an unrecognized shape; regression in the evaluate snippet string (escaping errors); browser tab closed mid-verification.
