Gio.DBusMessage.prototype.to_gerror

function to_gerror(): Boolean {
    // Gjs wrapper for g_dbus_message_to_gerror()
}
  

If message is not of type Gio.DBusMessageType.error does nothing and returns false.

Otherwise this method encodes the error in message as a GLib.Error using Gio.DBusError.set_dbus_error using the information in the Gio.DBusMessageHeaderField.error_name header field of message as well as the first string item in message's body.
