An administrator may desire to give a REST host a user friendly name in the orchestrator-ui web GUI. The name of a REST host may be changed in the Assets>Resources tab which leads to workflows associated with that host later disassociating with that host because the UUID changes when another host is later added.

This is by design and expected behavior.
The name is supposed to match the ID as designed, which is how the API reference is derived.
Currently, the REST host must be re-associated with any workflows that previously referenced the host prior to the UUID changing.
This behavior will be enhanced in the future to allow for a user friendly name to be set without modifying the ID and API references.
