Mongodb bulk write error

Question

I'm executing bulk write

bulk = new_packets.initialize_ordered_bulk_op()

bulk.insert(packet)

output = bulk.execute()

and getting an error that I interpret to mean that packet is not a dict. However, I do know that it is a dict. What could be the problem?

Here is the error:

    BulkWriteError                            Traceback (most recent call last)

    BulkWriteError: batch op errors occurred

Answer 1

Ok, the problem was that i was assigning _id explicitly and it turns out that the string was larger than 12-byte limit, my bad.
