The request must include at least one narrowing filter.
422 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

A rollup/aggregation request was submitted without any of the required narrowing filters, which would force a full-dataset scan. The response detail lists the acceptable filters.

​
How to fix

Add at least one of the listed filters (e.g. jurisdiction, state, metro_cbsa, date range) and resubmit. Not retryable — fix the request before resubmitting; retrying unchanged returns the same error. 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.
