400 — Invalid parameters

400 Bad Request

One or more parameters are wrong.

/v1/*: { "error": { "type": "invalid_request", "message": "Ugyldige parametre", "code": 400, "details": { "issues": [{ "path": "…", "message": "…" }] } } }

/dawa/*:

{ "type": "QueryParameterFormatError",
  "title": "One or more query parameters was ill-formed.",
  "details": [["betegnelse", "Param skal være…"]] }

Fix:

1. Read issues/details — they point at the wrong field.
2. Check required parameters (e.g. q on autocomplete; lat+lon on /v1/reverse; x+y on /dawa reverse).
3. per_side must be an integer within the allowed range: up to 100 on /v1/adresser (autocomplete uses limit, up to 50), up to 1000 on /dawa/*.
4. /v1/adresser rejects unknown parameters (e.g. side or struktur) with 400 — they only exist on /dawa/*.

Note: an unknown srid gives 400 on /v1/*: "Ugyldig srid — understøttede værdier er 4326 (WGS84, default) og 25832 (UTM 32N / ETRS89)". See "Coordinate systems (EPSG/srid)".
