Fails on calling host.name(),

Help understanding why this is happening is welcome.

The error is not about calling 'host.name()' - the stack trace only shows part of the code [1].
The actual problem seems to be during deployment process - please take a look at stderr
of the dnf commands (both hosts and the engine seem to be affected):

above stderr looks ok, dnf is importing missing gpg keys to validate the rpm signing.

I don't really see the error there.
Are these warnings also ok?

yes, rpms are being installed from external repos and yum is importing gpg keys from those repos when it encounters a rpm signed with an unknown key for checking it.
