tpm2-abrmd has no valid nodes in dbus

[xcgj]

I compiled tpm2-abrmd based on tpm2-abrmd-3.0.0 and used tpm2-tss-4.0.1 as the dependency library.
The tpm2-abrmd service is compiled and installed by running the following command:

$ ./configure --enable-debug=yes --disable-silent-rules --enable-dependency-tracking --disable-dlclose
$ make
$ sudo make install
$ sudo ldconfig
$ sudo pkill -HUP dbus-daemon
$ systemctl daemon-reload

However, the tpm2-abrmd service was not automatically started successfully.
So I started the tpm2-abrmd service manually using 'systemctl start tpm2-abrmd' command.
After starting, tpm2-abrmd can be found in dbus-daemon:

# dbus-send --system --dest=org.freedesktop.DBus --type=method_call --print-reply /org/freedesktop/DBus org.freedesktop.DBus.ListNames
method return time=1705496956.554515 sender=org.freedesktop.DBus -> destination=:1.70 serial=3 reply_serial=2
   array [
      string "org.freedesktop.DBus"
      ......
      string "com.intel.tss2.Tabrmd"
   ]

But when querying the dbus which methods tpm2-abrmd supports, the dbus returns this message:

# dbus-send --system --dest=com.intel.tss2.Tabrmd --type=method_call --print-reply /com/intel/tss2/Tabrmd/Tcti org.freedesktop.DBus.Introspectable.Introspect
method return time=1705496833.375409 sender=:1.69 -> destination=:1.68 serial=7 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 2.68.1 -->
<node>
</node>
"

I think there is a problem with DBus returning empty node. Is there any solution?
