application/problem+json. Branch on type (a stable URI), not on title
or detail (human-readable, may change).
When it occurs
The slug is not present in thejurisdictions table. On /v1/jurisdictions/{slug}/cohorts/distribution this is a 404; on /v1/territory/rollup an unknown slug in a filter returns 422 instead.
How to fix
Use a canonical slug (any slug that returns200 from the cohort-distribution endpoint). See Jurisdictions.
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.
