Adding a plugin to krunner gives dbus error

I’m trying to add a script/plugin to krunner under Plasma 6 on Kubuntu 24.10. I had this working on Plasma 5/Kubuntu 24.04. So I’m using the template folder as a starting point from github: runner6python template

But the install script gives:

"Quitting application krunner failed. Error reported was:\n\n     org.freedesktop.DBus.Error.NoReply : Message recipient disconnected from message bus without replying"

Is this me? Or should I raise as a bug against this template in krunner?
