question about mongoose geospatial query and aggregation

[Satyen Dhingra]

I am trying to run a query and want to aggregate results based on location, 

here is the query + aggregation

let qry = Users.find(); 

qry.where('userType').equals('provider'); 

qry.where('firstName').equals(firstName); 

  let ret = await Users.aggregate().near( 

                 {    near: [lng, lat], 

                      maxDistance: radiusInMiles * MILES_TO_METERS, 

                      distanceField: 'distance', 

                      query: qry 

                     } ).exec();

when I try to run this, I get a "cyclic dependency detected" error, any ideas...
