I am trying to use kdeconnect-cli to send SMSs, since there is not support (apart from replying) to do it from the GUI.

Unfortunately, I find that most kdeconnect-cli commands always reoprt the following message when executed, even if they are successful:

error activating kdeconnectd: QDBusError("", "")

Today I sent 5 identical SMSs to a friend of mine because of this: the command had succeeded, but kdeconnect-cli would report error.

I would like to write a little GUI program to let users send SMSs through kdeconnect, but it is impossible to do so if I don't know whether the command was successful or not.
