i have also the same issus with my copy activity in microsoft fabric. Should I check if there are specific permissions for Microsoft Fabric to access my mongodb atlas collection? I successfully retrieved data via a Python script and added my IP to the list of IPs.

I’m trying to copy data via a pipeline using Microsoft Fabric to retrieve my MongoDB Atlas collection. I had an error that I corrected by adding a parameter that allows access to all IPs to access the MongoDB service. After running the test, I now encounter a new error that appears (progress… :)). I’m coming to you to ask if you could explain where this new error might be coming from. Thank you for your help.
