MongoServerError during a new TR181 device activation

1

Hello Guys!

I am trying to activate a new device on my ACS here, but i am receiveing an MongoServerError…

Tha CPE is a BluCastle “UNG221E” model, this is a TR181 device and the XML it sends to ACS is this:

On my ACS logs(tail -f genieacs-cwmp-access.log) i only can see this message:
“2022-12-15T10:31:51.451Z [ERROR] ::ffff:179.104.54.92 8CBA25-UNG221E-FTTH05B84220: CPE already in session”

And looking at the Forum and other cases here, i found a comment to look at “journalctl -f | grep cwmp” and this is what i found:

coould it be the last one?

       <ParameterValueStruct>
                        <Name>
                            </Name>
                        <Value
                            xsi:type="xsd:string">
                            </Value>
                        </ParameterValueStruct>
                    </ParameterList>

no name on it, I guess that’s why Mongo complains.

I know nothing about that device, but I would try to reproduce the problem in a contained enviroment.

That was my first thought, which must be something related to that…
And if so, is there any way to fix this via ACS? or in this case I should speak directly with the manufacturer (BluCastle) for them to correct the information inside the TR069 inform?

Thanks a lot in advance!

Provide all the evidence to the mfgr and have them fix it. Workarounds for crappy implementations are sub-optimal. I’ve had luck getting mfgrs to fix their stuff by pointing to the exact line of the spec they are violating.
