Java.lang.IllegalArgumentException: BasicBSONList can only work with numeric keys, not: [_id]

After another SO poster (Vinicius Miana) resolved my problem , insert List[DBObject]...

// Bulk insert all documents
collection.insert(MongoDBList(docs)) // docs is List[DBObject]

Now I see this error when trying to insert.

java.lang.IllegalArgumentException: BasicBSONList can only work with numeric keys, not: [_id]

EDIT

I checked the post with my same problem, but I'm not sure how to apply the accepted answer.

Does this error mean that I cannot insert key-value pairs in such a way that it is valuenot hidden before Int(behind BasicBSONList )?

I would recommend this approach is not needed! Here is what you need to do. Get a job SalatDAOor ModelCompanion- see https://github.com/novus/salat/wiki/SalatDAO and https://github.com/novus/salat/wiki/SalatWithPlay2 .

Here's an example implementation SalatDAOfor a model object named MyObject:

object MyObjectDAO extends SalatDAO[MyObject, ObjectId](collection = MongoConnection()("my_test_db")("my_test_coll"))

Then just insert your documents with SalatDAO#insert(docs: Traversable[ObjectType], wc: WriteConcern = defaultWriteConcern)

MyObjectDAO.insert(docs)
