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.






python-3.x mongodb pymongo

          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}}}])
