Hi I have the following requirement.Somebody plz help me.

I am doing a mongodb aggregate operation for which my final data looks like below

{
 "data":{
},
  "subdata":[{}]
}

For some reason I would like to get the final result as

{
  "data":{
    "subdata":[{}]
  }
}

I tried several ways.It is not working as I expected.

PS:I am not using mongoose.
