Uhm. That’s the first time I see that and I definitely would not recommend to
try it that way. You _can’t_ create Zone and Endpoint objects via config sync,
you *need* to define them on the client itself prior to establish a connection
to between the master and the client.

Yep, that’s correct. It is not allowed to create objects in the context of
creating another object.
As said, build your endpoint and zone objects on the client itself. I did write
some docs to explain that.
