filter returns empty result (possible issue with SRID)

[andilabs]

the postgraphile query:

query findNearby($point: GeoJSON) {
      allApiDjtinderusers (
        filter: {
          lastLocation: { equals: $point }
        }) {
        nodes {
          id
          lastLocation {
        		geojson
        		srid
        		y
        		x
      		}
        }
      }
    }

the variable:

{
  "point": {
    "type":"Point",
    "coordinates":[20.9800552409116,52.2724808126503],
    "crs": {"type": "name", "properties": {"name": "EPSG:4326"}}

  }
}

the result:

{
  "data": {
    "allApiDjtinderusers": {
      "nodes": []
    }
  }
}

There exist record with given 20.9800552409116,52.2724808126503 coordinates, so I would expect getting it in result of equals query.

Additional info for reference:

I first created a point, and then used equals query, got the correct result @andilabs
