Confusing error message with resolvconf DNS manager

[QazerLab]

Describe the problem

I'm facing a behavior that seems a bit strange for me (as a user), and I'm not sure how to treat and fix the error below.

There is a netbird network with some private hosts behind it and a private DNS server is set up in this network to resolve private domain names for these hosts. I can connect to this network successfully, but it seems that netbird refuses to change my local DNS settings, if I use openresolv:

ERRO client/internal/dns/server.go:322: unable to configure DNS for this peer using resolvconf manager without a nameserver group with all domains configured
...
ERRO [nameservers: [{10.200.0.2 udp 53}]] client/internal/dns/server.go:525: Failed to apply nameserver deactivation on the host: unable to configure DNS for this peer using resolvconf manager without a nameserver group with all domains configured

However, if I switch from openresolv to systemd-resolved, everything works fine (DNS traffic for private domains is routed to netbird's wt0 interface and then, I believe, netbird somehow forwards it to the destination DNS server advertised by the network):

$ resolvectl status
...
Link 4 (wt0)
...
Current DNS Server: <wt0 address>
DNS Domain: [<private domain zones list>]

$ netbird status -d
OS: linux/amd64
...
Nameservers:
  [10.200.0.2:53] for [<private domain zones list>] is Available

My question is: given that network itself is fully functional (and everything works well with a different DNS manager), what is the problem with openresolv? I'm not sure how to interpret the error message above and what does it mean at all; I believe that the error reason is trivial, but the error message seems to be somewhat obscure to me.
