Gio.DBusError: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist

[sidevesh]

This happens when I launch https://github.com/ThePBone/GalaxyBudsClient,

this error does not have any immediate effect but when I Lock and Unlock the session or Disable and Reenable the extension, the indicator of this app vanishes and never appears back, I can confirm the app is running and closing and opening the app again shows the indicator again.

Full error seen in journalctl:

Well, if an app doesn't implement the standard freedesktop DBus properties specifications is hard for us to get infos...
