    Variable idsProblemConst

    idsProblem: Problem = ...

    The occupation ids (ids): one or more dkzIds, comma-separated, each a whole number of digits (at least 1). The API answers a non-numeric id, and an empty item from a trailing comma (9162, — the classic output of a script that joins ids), with a bare HTTP 400. Space around an item is fine (normalizeIds trims it).
