I am trying to fetch data from mongoDB using graphql and Meteor. Unfortunately it returns null for some fields where there is a value in the database. This is only happening in Production and Staging environments, which are hosted at mongoDB Atlas. The exact same query is returning the value correctly when connected to a local mongoDB instance. This issue persists when we have the same code deployed on a server at Meteor Galaxy. Has anyone experienced something similar? I would really appreciate it if anyone could help.
