query not working on geojson

[jmpmcmanus]

Hi = I have not able to query geojson data. Below is an example of geojson data:

When I run the query: http://localhost:8000/drf/api/pfas_in_tapwater_usgs/?query={properties{pfos,pfoa}}&format=json

it returns the following message: ["properties field is not found"]

I tested it on regular json data and it worked. Below is an example of regular json data I queried:

I ran: http://localhost:8000/drf/api/ahhs_dust_data/?query={pfos_concentration,pfoa_concentration}&format=json

and it returned data. It was able to access the variables under results, but could not access the variables under features in the geojson case?

Thanks!
Jim
