Error message

Dianping member page rendered but no user_id link found — stale dper or layout drift

What it means

CommandExecutionError raised when the Dianping member page renders but the DOM scrape finds no /member/<digits> profile link, so no user_id can be extracted. The library assumes either the dper session is stale (page rendered a logged-out shell) or Dianping's page layout changed. It is a scraping-contract failure, not an auth error per se.

Solutions

1. Re-login to refresh the dper session, then retry — a stale session often renders a logged-out page without the profile link.
2. Increase the wait before evaluate (wait for the .user-name/.member link selector instead of a fixed 2s) and retry.
3. Inspect the live page HTML and update the selectors in auth.js (nickname/user_id extraction) if Dianping changed its layout.
4. Save the page HTML/screenshot on failure to distinguish layout drift from a bot/verification page.

Example fix

// before
await page.wait(2);
const info = await page.evaluate(...);
// after
await page.waitForSelector('a[href*="/member/"]', { timeout: 10000 }).catch(() => null);
const info = await page.evaluate(...);

await page.waitForSelector('a[href*="/member/"]', { timeout: 10000 }).catch(() => null);
// only then call verify

function extractUserId(html) { const m = String(html||'').match(/\/member\/(\d+)/); return m ? m[1] : null; }

try { identity = await cli.dianping.verify(); }
catch (e) { if (e.name === 'CommandExecutionError' && /user_id link found/.test(e.message)) { await page.reload({ waitUntil: 'networkidle' }); identity = await cli.dianping.verify(); } else throw e; }

When it happens

Trigger: verifyDianpingIdentity loads /member/myinformation, passes the login-redirect check, but page.evaluate returns {user_id: ''} because no anchor matching a[href*='/member/'] with /member/\d+ exists in the DOM.

Common situations: Dianping redesigned the member page selectors; page still loading when evaluate runs (fixed 2s wait too short); logged-out or bot-challenge variant of the page rendered; regional/AB-tested layout without the profile link.
