Error message

Trip.com poiSearch fetch failed: ${err instanceof Error ? err.message : String(err)}

What it means

fetchPoiSearch wraps the underlying fetch() to the Trip.com poiSearch endpoint. If fetch itself throws — network unreachable, DNS failure, TLS error, connection reset, timeout — the error is re-thrown as CommandExecutionError prefixed with 'Trip.com poiSearch fetch failed:'. It is distinct from HTTP status errors, which are reported separately.

Solutions

1. Check network connectivity and DNS for the Trip.com API host (curl -v the endpoint)
2. Retry — the error is often transient; add backoff around the CLI invocation
3. If behind a proxy, set HTTPS_PROXY and ensure the proxy CA is trusted (NODE_EXTRA_CA_CERTS)
4. Read the inner err.message in the thrown text to identify the exact cause (ENOTFOUND, ECONNRESET, certificate, etc.)

Example fix

// before
await tripcli(['attractions-search','--query','Kyoto'])  // offline laptop
// after
// connect/VPN first, then retry with backoff
await retry(() => tripcli(['attractions-search','--query','Kyoto']), {retries:3, backoff:1000})

// pre-check connectivity before invoking
try { await fetch('https://www.trip.com', { method: 'HEAD' }); } catch (e) { throw new Error('network unavailable: ' + e.message); }

null

try {
  const results = await searchAttractions(keyword);
} catch (e) {
  if (/poiSearch fetch failed:/.test(e.message)) {
    if (/ENOTFOUND|ECONNRESET|ETIMEDOUT/.test(e.message)) return retryWithBackoff(() => searchAttractions(keyword), 3);
    if (/certificate|CERT/.test(e.message)) { process.env.NODE_EXTRA_CA_CERTS && console.error('check CA bundle'); }
  }
  throw e;
}

When it happens

Trigger: Calling any command path that goes through results -> fetchPoiSearch while offline; DNS cannot resolve the Trip.com API host; a proxy/firewall blocks the request; Node lacks a trusted CA for the TLS handshake; transient connection reset mid-handshake.

Common situations: Corporate proxy intercepting HTTPS; VPN dropping mid-request; missing NODE_EXTRA_CA_CERTS on corporate networks; IPv6 misconfiguration; rate-limit-induced connection drops at the network layer.
