Error message

auth

What it means

AuthRequiredError('coupang.com') thrown by verifyCoupangIdentity when the in-page probe of https://www.coupang.com/np/mypage reports kind 'auth'. This happens when mypage redirects to login.coupang.com/login (anonymous session despite cookies), Coupang returns 'Access Denied' (anti-bot or non-KR IP), or the mypage loads with HTTP 200 but no member-name element is found. Any of these mean Coupang does not consider the session a valid logged-in member.

Solutions

  1. Re-login in the controlled Chrome (coupang auth login coupang) to refresh the session
  2. Check the probe.detail in the error: 'redirected to login' → re-login; 'Access Denied' → use a KR/residential IP or slower polling; 'no member-name surface' → update the name selectors to match current mypage markup
  3. Avoid datacenter IPs and headless flags that trip Coupang anti-bot
  4. Wait and retry if the block is transient rate-limiting

Example fix

// before
 coupang auth verify coupang  # AuthRequiredError: Access Denied — anti-bot or non-KR IP
// after
 # route Chrome through a KR residential proxy, then
 coupang auth verify coupang
Defensive patterns

Strategy: try-catch

Validate before calling

// probe mypage reachability before verify
const res = await fetch('https://www.coupang.com/np/mypage', { redirect: 'manual' });
if (res.status === 403 || /Access Denied/i.test(await res.text().catch(() => ''))) {
  throw new Error('Coupang blocking this IP — use a KR/residential proxy');
}

Type guard

function isAuthProbe(probe) {
  return probe != null && typeof probe === 'object' &&
    probe.kind === 'auth' && typeof probe.detail === 'string';
}

Try / catch

try {
  const identity = await coupangVerify(page);
} catch (err) {
  if (err instanceof AuthRequiredError) {
    if (/Access Denied/.test(err.message)) {
      proxy.rotateToKRResidential();  // geo/anti-bot block
    } else {
      await coupangLogin(page);       // redirected to login
    }
    return coupangVerify(page);
  }
  throw err;
}

Prevention

When it happens

Trigger: Session cookies exist but are expired/invalid so mypage redirects to login; anti-bot 'Access Denied' page; mypage markup changed and selectors (.my-nickname, .member-name, .mp-user-info-name, [class*=memberName]) match nothing.

Common situations: Running verification from a datacenter/non-KR IP triggering Coupang's geo/anti-bot block; stale cookies passing the cookie check but rejected server-side; Coupang redesign changing nickname element classes; headless fingerprint detected.
