GridFSStore collection has no database attribute

[pmiam]

Any atomate2 TaskDocument larger than the document limit cannot spill into gridfs additional stores successfully because the gridfs collection has no database property

Traceback (truncated):

I deployed the official docker container on an enterprise server.

conda list (truncated)
jobflow 0.1.7 pyhd8ed1ab_0 conda-forge
maggma 0.49.4 pyhd8ed1ab_0 conda-forge
atomate2 0.0.1.post912+g1fd2322 pypi_0 pypi (my fork main)
pymongo 4.2.0 pypi_0 pypi

In context, I've written a very simple script to try backfilling a database with legacy vasp runs, obviously there's some shortcomings to this, but this cannot be one of them. Very new to all this. Advice appreciated.

Hi @PanayotisManganaris. I will take a look at this.
