Hi, a very blind guess, not really tested: Try putting quotes around count, i.e. { "count-visible": true, "count": 1 }

Hi all, I'm writing a Kwin script to automatically set an unread count badge to an app's launcher icon by parsing its title. I'm stuck at the part where I need to call an DBus API, but always get "Received D-Bus message is error". I appreciate any help to show me where I got it wrong, or callDBus just doesn't support passing a{sv} argument yet. This is the method that I need to call: https://wiki.ubuntu.com/Unity/LauncherAPI#Low_level_DBus_API:_com.canonical.Unity.LauncherEntry <https://wiki.ubuntu.com/Unity/LauncherAPI#Low_level_DBus_API:_com.canonical.Unity.LauncherEntry> I can use gdbus and it successfully update the launcher's icon badge: gdbus emit --session --object-path /com/canonical/unity/launcherentry/1 --signal com.canonical.Unity.LauncherEntry.Update "application://chrome-ebcgcbpjedmohalnmiodnfidggpfcehe-Default.desktop" "{'count-visible': <true>, 'count': <2>}" But when I attempt to use callDBus in my script, it fails: callDBus( "com.canonical.Unity", // Service "/com/canonical/unity/launcherentry/1", // Path "com.canonical.Unity.LauncherEntry", // Interface "Update", // Method "application://chrome-ebcgcbpjedmohalnmiodnfidggpfcehe-Default.desktop", { "count-visible": true, count: 1 } ); I tried to read the source code of callDBus and failed to understand whether it supports a{sv} or not, since I'm not familiar with Qt and C++. https://invent.kde.org/plasma/kwin/-/blob/master/src/scripting/scripting.cpp#L253 <https://invent.kde.org/plasma/kwin/-/blob/master/src/scripting/scripting.cpp#L253> Thanks in advance for any help.
