this one is a blocker since if you drag a project to a server or use run as then it will keep giving NPE's and removal is broken too.

Fixed in M4 by ignoring projects/units without a git repo.

Looking at the logic of this then the dialog is shown for every module even if those modules are same git repo - that should be detected/handled somehow.

And possibly resources without a git repo should be rejected.

note, git repo's can still disappear in case users remove the git repo or git feature from project.
