WLST in Cluster - Try to use server name with application name. Multiple server targets deployed for application

While running WLST for policy related commands in single server domain, it worked fine.

When running in domain with multiple server, it failed with error message:
Try to use server name with application name. Multiple server targets deployed for application

Resolution is quite simple, run it against one node or each node:
