I have created a subclass from BsonDocument as below

public class MyClassDocument : BsonDocument
{

}

But, MyClassDocument class is not getting serialized while making calls to any of the API methods,

Error Message:
MongoDB.Driver.MongoCommandException: Command insert failed: error parsing element 0 of field documents :: caused by :: wrong type for '0' field, expected object, found 0: [ {}, {} ]
