NameHasNoOwner DBus error

[medeotl]

I can build the code correctly and execute the program with "com.example.Gtk.JSApplication" , but when I launch it from the desktop environments (Gnome) it doesn't start. Looking at .application file, it try to execute gapplication launch com.example.Gtk.JSApplication and if I do this command I get this error: error sending Activate message to application: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Could not activate remote peer.

No idea how I can try to fix this

Hi! Thanks for your report.

How did you install the app? Did you install the .service file in the correct dbus directory? What happens if you run "com.example.Gtk.JSApplication" from the command line?

Also, if you're running dbus-broker (Fedora 30), on occasion it helps to run:

gdbus call --session --dest org.freedesktop.DBus --object-path /org/freedesktop/DBus --method org.freedesktop.DBus.ReloadConfig

after installation, or alternatively logout/login

HI, thank for your help.

How did you install the app?

not sure, but I think with the usual meson build --prefix=/usr, ninja, ninja install

Did you install the .service file in the correct dbus directory?

not on my own

What happens if you run "com.example.Gtk.JSApplication" from the command line?

it start and run without any problems

Also, if you're running dbus-broker (Fedora 30), on occasion it helps to run

yes I'm on Fedora 30, giving the command doesn't solve the issue.

I've tryed to clone the repository and rebuild the code, and I've got this error:
