What problem are you facing?

Hi,
I’ve encounter an issue while using bulkWrite method with a transaction session.
My operations includes 2 documents insertion and 6 updates.
When using the same operations without bulkWrite, everything works as expected.
The error seems to be thrown from one of mongodb dependencies called “bson”.

What driver and relevant dependency versions are you using?

I’m using NodeJS driver with mongodb dependency version of “3.6.2”
This mongo version uses “bson” dependency with version of “^1.1.6”.

Steps to reproduce?

It's not something that occurs all the time so I don't have a clear way on how to reproduce it.
