Why does MongoDB return duplicate records even with a unique index in place?Why does MongoDB return duplicate records even with a unique index in place?

I’m working on a project using MongoDB and have created a unique index on one of my collections. Despite this, I’m still seeing duplicate records in my queries. Is this expected behavior? Am I missing something with the configuration of the unique index? Any insights or advice on how to troubleshoot this would be really helpful!

Can you share your index specifications, query, and returned duplicate documents?
