Vsivsi:file-collection replacement - SOLVED

I have several small meteor apps build with Meteor 2.7.3 running on ubuntu 18.04, and I decided to start to redeploy them to a new Ubuntu 22.04 server.

Unfortunately, I have now discovered that the atmosphere package vsivsi:file-collection, which is no longer supported by the author, uses mongo commands that are no longer supported on Mongodb 6.

For those that may have used vsivsi:file-collection in the past, what did you replace it with? And does Meteor 2.7.3 even support Mongodb 6?

Meteor doesn’t support MongoDB 6, so I downgrade to 5, and it works.
