Cannot access `properties` key/value content when querying ArcGIS Feature Service for GeoJSON

DevonKoch — Thu, 18 Jun 2020 08:35:22 GMT

Using ArcGIS with a developer account, I created a new layer, uploaded a .geojson file, and happily followed along the "query a feature layer" tutorial on their labs site. I successfully generated an OAuth Token in Postman, but when I changed the "f" (format) value in the x-www-form-urlencoded body to "geojson" it looks similar to the originally geojson file, but the properties are missing/null and the only key info included are the Polygon coordinates. The data remains in the ArcGIS Dashboard but isn't included in the data. Any advice? Is this a bug?

Original File (.geojson):

{   "type": "FeatureCollection",   "features": [{     "geometry": {       "coordinates": [         [           [50.0115001901903, 50.2259915257836, 0],           [50.0115418500254, 50.225991583611, 0],           [50.0115447598285, 50.2242567612666, 0],           [50.0115031005844, 50.2242567034437, 0],           [50.0115001901903, 50.2259915257836, 0]         ]       ],       "type": "Polygon"     },     "ID": "asdf98d0-fa90-4293-a780-a6988f5486f7",     "id": 1,     "type": "Feature",     "properties": {       "CreationDate": "Wed, 17 June 2020 18:40:41 GMT",       "Editor": "dkoch"     }   }] }
