If collection owns data of different bson type 1 (double) and 16 (32 bits integer), I'm getting the given exception

Data:

// 2 documents in the collection
> db.test.find().pretty()

{ "_id" : ObjectId("5622bcebf9f16d8b892d498e"), "MoyLignesPreparees" : 0 } { "_id" : ObjectId("5622bcebf9f16d8b892d498d"), "MoyLignesPreparees" : 0.5 }

// 2 types of data
> db.test.count({ "MoyLignesPreparees":

{ $type: 1 }
