The pre-flight cardinality check exceeded its timeout.
504 application/problem+json
Every PermitCore error is RFC 9457 application/problem+json. Branch on type (a stable URI), not on title or detail (human-readable, may change).

​
When it occurs

The guard that estimates result cardinality before running an aggregation exceeded its own timeout — usually a sign the filters are too broad.

​
How to fix

Narrow the filters and retry. Retryable — retry with exponential backoff (respect Retry-After on 429/503). See the full error catalog for the response shape and retry matrix. Every response carries an x-request-id header — include it in any support request.
