HTTP 422 · problem type
invalid-target
Invalid target.
A target selector is invalid: an unknown country code, a connection type other than fixed or mobile, or a connection type the operator does not have in that country.
What to do
Use ISO 3166-1 alpha-2 country codes in upper case (DE, PL, NO) and check GET /v1/geos/{country} for operators and connection types.
