Below is the error message:

ABORTED: Failed to establish connection: Couchbase.AuthenticationFailureException: Cannot authenticate the user. Reason: AuthenticationError 

Taken example of `Setup test Infra and Execute Tests / 7.1-stable Vs DOTNET_MASTER / com.couchbase.transactions.RbacOnCollectionsTest.readWritePermissionsOnCollectionsOfTxnOperationButOnlyWriteOnlyReadOnATRCollection` (the first Jenkins failure in above list) to show the driver and FIT Performer logs as they are not failing in local.

Attaching docker and IntelliJ logs for your reference. Please feel free to reach out for any further assistance.

Thanks!
