Original Pull Request: https://github.com/netbirdio/netbird/pull/7060

State: closed
Merged: Yes

Block deleting a group referenced as a source group by an agent network
policy, and drop unresolvable groups from synthesised private-service
ACLs. A deleted group survived in agent_network_policies.source_groups
and was carried into the injected in-memory policy, where network-map
assembly resolved it to a nil group and panicked on every proxy peer
sync.

Checklist

  • Is it a bug fix
  • Is a typo/documentation fix
  • Is a feature enhancement
  • It is a refactor
  • Created tests that fail without the change (if possible)
  • I ran and tested this change locally — I did not rely on CI to find out whether it works
  • This PR has a single purpose (not a fix + refactor + feature in one)
  • This change is a trivial fix, OR it links an issue the NetBird team agreed on beforehand. Changes to the public API, gRPC protocols, functionality behavior, CLI / service flags, or new features always need that agreement first. See CONTRIBUTING.md.
