Error message

HTTP ${probe.httpStatus} from nowcoder profile API

What it means

When the in-page probe's fetch to https://gw-c.nowcoder.com/api/sparta/user/profile/<uid> returns a non-OK, non-401/403 status, the probe reports kind:'http' and the library throws CommandExecutionError with 'HTTP <status> from nowcoder profile API'. This signals a server/gateway problem rather than an auth problem.

Solutions

1. Wait and retry after a delay (backoff) — 429/5xx are usually transient
2. Check https://www.nowcoder.com availability in a browser
3. If persistent 404, the endpoint changed; update WHOAMI_PROBE to the current profile API URL
4. Reduce call frequency to avoid rate limiting

Example fix

// before
const who = await verifyNowcoderIdentity(page);
// after
let who;
try {
  who = await verifyNowcoderIdentity(page);
} catch (e) {
  if (/HTTP 4\d\d|HTTP 5\d\d from nowcoder profile API/.test(e.message)) {
    await new Promise(r => setTimeout(r, 5000));
    who = await verifyNowcoderIdentity(page);
  } else throw e;
}

// Pre-check reachability before the authed call:
const res = await fetch('https://gw-c.nowcoder.com/api/sparta/health', { method: 'HEAD' }).catch(() => null);
if (!res || res.status >= 500) throw new Error('nowcoder gateway unavailable; retry later');

function isHttpProbe(p) { return p?.kind === 'http' && typeof p.httpStatus === 'number'; }

try {
  return await verifyNowcoderIdentity(page);
} catch (e) {
  const m = e.message.match(/HTTP (\d{3}) from nowcoder profile API/);
  if (m && (m[1] === '429' || m[1].startsWith('5'))) {
    await new Promise(r => setTimeout(r, 10_000));
    return verifyNowcoderIdentity(page);
  }
  throw e;
}

When it happens

Trigger: Profile API responding 429 (rate limit), 500/502/503 (gateway errors), or 404 (API path changed) while the user is logged in.

Common situations: Hitting the API too frequently (rate limiting); nowcoder gateway maintenance or outages; the sparta profile endpoint path being renamed after a nowcoder API update.
