Real-user performance data could not be retrieved

InfoConfirmedperf.crux.query-failed

What this check looks for

The Chrome UX Report API did not answer our request, so we have no real-user data to show. This is a failure on our side or Google's, not on yours.

It is reported rather than hidden so that a missing performance section is visibly a missing measurement, and not read as everything being fine.

This check never deducts. It reports a fact — or reports that something could not be verified — and is shown on the report without moving the score.

Technical detail

The query for ‹scope› failed: ‹reason›. ‹detail›

The common causes, all of which are ours to fix rather than yours:

**Quota** — the CrUX API is limited to 150 queries per minute per Google Cloud project, shared across every scan this deployment runs. A burst of scans exhausts it and the API answers 429. We cache field data per URL and per origin specifically to keep well inside that limit.
**An unreadable answer** — the API returned something that did not match the documented response shape. We report that rather than guess at what it meant.
**A transport failure or timeout** reaching chromeuxreport.googleapis.com.

Retrying the scan in a minute or two usually clears a quota refusal. Nothing about the site's performance is asserted either way.

Run the check that produces this finding, on its own, against any domain.
