As a consumer of the Ninja API, I want to select subsets of "geometry" fields, to have a consistent drilldown into API JSON responses

curl -X GET \
  "https://mobility.api.opendatahub.bz.it/v2/api/flat/ParkingStation?select=scoordinate.srid" \
  -H "accept: application/json"

gives

{
  "code":400,
  "message":"ERROR: operator does not exist: geometry #> unknown
    Hint: No operator matches the given name and argument types. You might need to add explicit type casts.
    Position: 35",
  "error":"Bad Request",
  "timestamp":"2020-03-30T09:21:43.270+0000"
}

Although, this is not JSON the consumer of the API might think that it is, so to be consistent from his point of view, we must support geometry drilldowns

@Piiit for a more complete description, this applies also to scoordinate.x and scoordinate.y (you know that, but others might not).

@stefanodavid Yes, what I mean with "geometry" is the scoordinate and pcoordinate field. That is something that is not supported yet...
