Issue while trying to execute Device Watchdog request in DiameterGateway in ECE

Hi ,

We are trying to execute device watchdog request in ECE DiameterGateway but getting  COMMAND_NOT_SUPPORTED error in DGW logs.

I have kept the command code as 280, as per RFC standards. Also confirmed from $ECE_HOME/oceceserver/config/diameter/dictionary_main.xml file entry for DW request is present as below:

<command name="Device-Watchdog" abbrev="DW" code="280">

            <request arbitrary-avps="false">

                <avprules>

                    <avprule name="Origin-Host" maximum="1" minimum="1"/>

                    <avprule name="Origin-Realm" maximum="1" minimum="1"/>

                    <avprule name="Origin-State-Id" maximum="1"/>

                </avprules>

            </request>

            <answer arbitrary-avps="false">

                <avprules>

                    <avprule name="Result-Code" maximum="1" minimum="1"/>

                    <avprule name="Origin-Host" maximum="1" minimum="1"/>

                    <avprule name="Origin-Realm" maximum="1" minimum="1"/>

                    <avprule name="Error-Message" maximum="1"/>
