Versions ``` txmongo==19.2.0 pymongo==3.0.3 ``` The `insert_many` method of `txmongo.collection.Collection` uses ``` bulk = _Bulk(self, ordered, bypass_document_validation=False) ``` But the `_Bulk` method in `pymongo 3.0.3` doesn't have the argument `bypass_document_validation` ``` class _Bulk(object): """The private guts of the bulk write API. """ def __init__(self, collection, ordered): ... ``` This causes the following error on using `insert_many` ``` File \"/usr/local/lib/python3.7/site-packages/txmongo/collection.py\", line 824, in insert_many bulk = _Bulk(self, ordered, bypass_document_validation=False) TypeError: __init__() got an unexpected keyword argument 'bypass_document_validation'"} ```
