Failed to push collection metrics command

Error message

Failed to push collection metrics command

What it means

Thrown when POSTing the enable/disable collection-metrics command to /_telemetry/commands fails (non-2xx, non-401). Causes mirror the other command pushes: malformed payload (collections list or interval not accepted), unknown target client/database, or a server-side 500. The server error body is used when present; the literal string is the fallback.

Solutions

1. Read the toast for the server's error string and correct the offending field (usually collection names or payload shape).
2. Refresh the client list and collection list, then re-select targets and retry.
3. If the toast shows the generic fallback, check the response body in devtools Network tab and the proxy logs for a 500.

if (!Array.isArray(collections) || collections.some(c => typeof c !== 'string' || !c)) {
    showToast('Collections list must be non-empty strings', 'error');
    return;
}

try {
  const resp = await fetch(url, { method: 'POST', headers, body });
  if (resp.status === 401) { logout(); return; }
  if (!resp.ok) {
    const error = await resp.json().catch(() => ({}));
    throw new Error(error.error || `Failed to push collection metrics command (HTTP ${resp.status})`);
  }
} catch (e) { showToast(e.message, 'error'); }

When it happens

Trigger: Toggling 'collection metrics' with an empty-but-invalid collections array, non-existent collection names, or a target client that disconnected between page load and submit.

Common situations: Collections renamed or dropped after the page loaded; targeting an evicted client; interval/enable payload fields inconsistent with the server's expected schema.
