Description
I'm getting the below error while using the log4j2 with mongo-driver-sync instead of mongo-java-driver. Although it's working fine with mongo-java-driver. I'm trying to upgrade my mongo db with 4.2 and i'm using mongo java driver 4.0 that is mongo-driver-sync. So i have removed all the previous dependencies including mongo-java-driver. But Logging started giving me the below Errors.
Error:
