Best Answer

Your mongod version is too old... For 2.5 BI connector

As said here!

The MongoDB Connector for BI and associated utilities are compatible only with MongoDB server version 3.2 or greater.

MongoDB Lookup Issue

Yes, you can use the $lookup operator as part of an aggregation, after you $unwind the batches array. For example:

db.collectionA.aggregate[

  { $unwind: "$batches" },

  { $lookup:
    from: "collectionB",
    localField: "batches",
    foreignField: "_id",
    as: "collectionB"
  }
]
