Hi, team, When I integrate mongodb I get this error: OperationFailure: Unrecognized expression '$bsonSize' mongodb version: 3.6.23

Hi there! It appears that $bsonSize is an aggregation operator that was introduced in MongoDb 4.4, as described here. It is used on this line of the MongoDB connector. I think this means that our connector requires Mongo 4.4 or above. We will need to update the doc here to reflect that

Yes, so it's not going to be compatible with versions <4.4?

As of today, it appears not. Maybe there's an easy way to make this compatible with earlier versions. @chilly-holiday-80781 If I recall, you'd worked on this previously. Do you know of any other gotchas preventing us from supporting earlier versions?

Hmm I’m not aware of this bug or any version gotchas, but I believe @miniature-tiger-96062 wrote this piece on using the $bsonSize operator. By the way @rhythmic-sundown-12093 – a couple of your credentials are exposed on this stack trace, so you may want to delete/censor it.

Hi all, We introduced a bsonSize aggregation recently to account for documents more that 16MB. I will take a look at how this can be supported for mongodb earlier versions and update this thread.

@chilly-holiday-80781 Thanks, I delete the log.txt
