facebook bmc how to use dbus?

[jack206]

I deployed the smbios-mdr component in the bmc of facebook, and the following error was reported when I ran it. How can I solve this?

root@bmc.:~# smbiosmdrv2app
terminate called after throwing an instance of 'sdbusplus::exception::SdBusError'
  what():  sd_bus_request_name: org.freedesktop.DBus.Error.AccessDenied: Permission denied
