HTTP ${res.status} ${res.statusText}${msg ? `: ${msg}` : ''}

Error message

HTTP ${res.status} ${res.statusText}${msg ? `: ${msg}` : ''}

What it means

Error thrown when the cached-model scan for the serve panel fails at the HTTP level: GET /api/model/cached<params> answered non-OK. The handler reads the body text, tries JSON detail/error/message, and appends whatever it found to the status line, then renders a 'Cached model scan failed' panel with a Retry button.

Solutions

  1. Use the Retry button after fixing the underlying cause identified in the ': <msg>' suffix
  2. curl -i the same /api/model/cached URL with params to see the full body
  3. Verify filesystem permissions on the models cache directory (and SSH reachability if host-scoped)
  4. Check backend logs for the scan exception
Defensive patterns

Strategy: retry

Try / catch

try {
  const res = await fetch(`/api/model/cached${params}`);
  if (!res.ok) {
    const body = await res.text().catch(() => '');
    let msg = '';
    try { msg = JSON.parse(body)?.detail || ''; } catch { msg = body; }
    throw new Error(`HTTP ${res.status} ${res.statusText}${msg ? ': ' + String(msg).trim().slice(0, 200) : ''}`);
  }
  const data = await res.json();
  if (data?.error) throw new Error(data.error);
  _writeCachedModelScan(scanSig, data);
  _dlWp.destroy();
  _renderCachedModelsData(list, data, host);
} catch (e) {
  _dlWp.destroy();
  renderScanFailureWithRetry(list, e.message, () => _fetchCachedModels(true));
}

Prevention

When it happens

Trigger: GET /api/model/cached returns 500 (backend scan of the models directory crashed — permission denied, disk error, huge directory timeout), 502/504 behind a proxy, or the scan is pointed at a remote host via params whose SSH connection failed.

Common situations: Models directory on a network mount that dropped; scan of a remote cache host whose SSH credentials changed; response body too large/slow triggering gateway timeout; backend updated and the route contract moved.
