Requests that fail alongside an error
Which fetch/XHR endpoints fail in the pageviews this error signature fires in.
Answers the detail-less rejection: the error carries no message and no frame, the failing request carries the URL, the method and the status. The two are never linked per event, so the answer is a correlation with a baseline, and the response says so.

application/json- response
Response for /analytics/error-types/correlated-requests.
The endpoints are ranked by lift, not by share: an endpoint that fails in 85 percent of all pageviews correlates with every signature at about 85 percent, and reading that as a cause is the mistake this endpoint exists to prevent. It reports co-occurrence, never causation.
meta*Facts about the result
request*The request as the server resolved it
surface*SurfaceWhich fetch/XHR failures were counted, chosen from the signature's message_kind: 'network' (status 0), 'aborted' (cancelled calls and status 0), 'http' (4xx and 5xx) or 'failures' (5xx and status 0, the default). 'aborted' answers 'the response was empty' and therefore covers two causes: a visitor who left and a call that never connected. Only the first is not a failure, and pageviews_cancelled on each row says how many of its pageviews were which.
message_kind*Message KindThe signature's recognised message shape, '' if unrecognised
summary*The two populations the shares are measured against.

fetch_xhr_collected*Fetch Xhr CollectedFalse when an application in scope does not collect fetch/XHR. The query then covered only the sites that do, so the numbers are sound but partial, and an empty list is inconclusive rather than an answer: request telemetry is opt-in, and nothing reconstructs a failing request from the error alone.
