With more recent versions of gjs, you could register your GError
domain and throw that. GDBus then would do the rest.
In 3.4, you can use a partial hack:
e = Error(message);
e.name = 'net.connman.Agent.Error.Retry';
throw e;
or you can make your method async, and use the GDBusMethodInvocation directly:
FooAsync: function(parameters, invocation) {
   if (ok) {
      invocation.return_value(GLib.Variant.new(...));
   } else {
      invocation.return_dbus_error('org.dbus.foo', 'message');
   }
}
