    Variable baseUrlApiPathProblemConst

    baseUrlApiPathProblem: Problem<unknown> = ...

    A base URL must not already end in the API path, in the current or the old spelling (/api/air-data/v3, /api/air_data/v3): the client appends it, so the API's documented address would request /api/air-data/v3/api/air-data/v3/... and get a 404. The reason names the host to use instead. A value that does not parse passes here (the engine reports it).
