I was trying to add a MongoDB Atlas connection and on clicking the test connection button, I am getting an error “[unauthorized] not authorized on local to execute command”. I tested the connection string and credentials in Mongo Compass and there it was working fine. So, I could not understand why the test connection is failing. After many tries, I just thought of saving the connection as it is and try it in the pipeline. Magically when used in the pipeline I was able to fetch the data from MongoDB. Then again when I tried the test connection and was getting the same error.
