node.js - MongoDB geospatial query does not return anything -

i have collection 2dsphere index , want use $geowithin , $centersphere functions query it.

excerpt of model:

{ // ... coordinates: {     coordinates: {         type: array,         index: '2dsphere'     } } // ... } 

i inserted bunch of documents database , try query via:

model.find({     coordinates: {         coordinates: {             $geowithin: {                 $centersphere : [ [ lng, lat], r ]             }         }     } }) 

the problem facing is, call not return anything, neither error, nor data. tried in mongo shell in node.js application longitudes , latitudes of objects can confirm inserted database. tried use $near $maxdistance same result. furthermore switched latitude , longitude check...and convert r radians dividing earth's radius.

i out of ideas on goes wrong @ point , thankful suggestions!

i think should change model but, use "dot notation" instead:

model.find({     "coordinates.coordinates": {         "$geowithin": {             "$centersphere" : [ [ lng, lat], r ]         }                 } },function(err,callback) {  });
