Fiware Orion: Geoqueries do not work for geojson polygons, only points seem to work

Question

I am having issues with a geo query, it seems only to work if the stored entity location geojson type is of type "Point", but not for polygons.

I am running Orion 2.5.2 in docker

I tested both near

https://{{orion}}/v2/entities/?type=Building&georel=near;maxDistance:2000&geometry=point&coords=51.706774495,8.776277548

and also intersects/coveredBy:

https://{{orion}}/v2/entities/?type=Building&georel=intersects&coords=51.70683451303916,8.77602696418762;51.706462195326104,8.776386380195618;51.70663838176868,8.776847720146177;51.706965820787424,8.776482939720154;51.70683451303916,8.77602696418762&geometry=polygon

but orion always returns empty results for the example entry: I could not find any hints in the spec nor the orion manual that this only works for points. Seems like a bug to me

          [8.776530571, 51.706858417]
        ]
      ]
    }
  }
}

I could solve it. Turns out I had type "geojson" instead of "geo:json". Changing to the latter works now.
