suggest failed

Error message

suggest failed

What it means

The nowcoder suggest command's in-page script POSTs the query to the search-suggestion endpoint with credentials included. If d.success is falsy it throws Error(d.msg || 'suggest failed'); 'suggest failed' is the fallback message when the API returns no msg. It indicates the suggestion API refused the request.

Solutions

  1. Log in to nowcoder.com in the automated browser so credentials:'include' carries a session
  2. Simplify the query (remove unusual characters) and retry
  3. Retry later in case of rate limiting
  4. Capture the raw response and update the endpoint/body in clis/nowcoder/suggest.js if the API contract changed

Example fix

// before
if (!d.success) throw new Error(d.msg || 'suggest failed');
// after
if (!d.success) throw new Error('suggest failed: ' + (d.msg || 'code=' + d.code));
Defensive patterns

Strategy: retry

Validate before calling

const q = typeof query === 'string' ? query.trim() : '';
if (!q) throw new Error('suggest requires a non-empty query');

Type guard

function suggestOk(d){ return !!d && typeof d === 'object' && d.success === true && Array.isArray(d.data?.records); }

Try / catch

try { await run(['nowcoder', 'suggest', '--query', q]); }
catch (e) {
  if (String(e.message).includes('suggest failed')) { await sleep(2000); /* retry once, or check session */ }
  else throw e;
}

Prevention

When it happens

Trigger: Running `nowcoder suggest` when the suggestion endpoint responds success:false without a msg — empty/odd query payloads, missing session cookie, endpoint renamed, or throttling.

Common situations: Unauthenticated browser session; Nowcoder changing the suggest endpoint or request body shape; special characters in the query tripping server validation; gateway incidents.
