I am trying to perform aggregate operation with Mongo which is like follows:



db.inbound_documents.aggregate([{"$match": 
{"$completed_on":
{"$gte":'2018-05-19 00:00:00',
"$lte":'2017-05-19 00:00:00'}}},
{"$group":
{"_id":"$completed_by","total":{"$sum":1}}}])


completed_on is available in the schema, Still I am not getting that why it is causing that error.

          just remove your $ sign before completed_on :



          db.inbound_documents.aggregate([
          {"$match":
          {"completed_on":
          {"$gte":'2018-05-19 00:00:00',
          "$lte":'2017-05-19 00:00:00'}}},
          {"$group":
          {"_id":"$completed_by","total":{"$sum":1}}}])
