bulk sync to node <some-string> failed

What does <some-string> defines? I was never able to find a node with id equal to <some-string>. How to map <some-string> to an actual node in my cluster?

Example log from journalctl

This answer explain how to map <some-string> to a particular swarm cluster Node. It would be nice to have it documented somewhere.
