I have RAUC integrated with a Yocto Morty build (Linux 4.14) running on an iMX7D (arm).  I'm trying to verify that the RAUC dbus interface is working, but I get an error when I use dbus-send:

# dbus-send --system --dest=de.pengutronix.rauc --type=method_call --print-reply /de/pengutronix/rauc de.pengutronix.rauc.GetSlotStatusError org.freedesktop.DBus.Error.UnknownMethod: No such interface 'de.pengutronix.rauc' on object at path /de/pengutronix/rauc

When I try introspection:

# dbus-send --system --dest=de.pengutronix.rauc --type=method_call --print-reply /de/pengutronix/rauc org.freedesktop.DBus.Introspectable.Introspect
method return time=1605228956.729035 sender=:1.6 -> destination=:1.8 serial=8 reply_serial=2
   string "<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN"
                      "http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd">
<!-- GDBus 2.54.3 -->
<node>
</node>
"

The RAUC service is on the system bus:

# dbus-send --system --dest=org.freedesktop.DBus --type=method_call --print-reply /org/freedesktop/DBus org.freedesktop.DBus.ListNames
method return time=1605229469.748648 sender=org.freedesktop.DBus -> destination=:1.13 serial=3 reply_serial=2
   array [
      string "org.freedesktop.DBus"
      string "org.freedesktop.login1"
      string "org.freedesktop.systemd1"
      string "de.pengutronix.rauc"
      string "org.freedesktop.Avahi"
      string ":1.13"
      string ":1.0"
      string ":1.1"
      string "org.freedesktop.network1"
      string ":1.2"
      string ":1.3"
      string "org.freedesktop.resolve1"
      string ":1.4"
      string ":1.6"
   ]

Any help with what I am doing wrong is appreciated.
