Serviio + qnapts212

Good evening,
I have a QNAp TS 212 and I installed Serviio qpkg.
I can’t add the Library, on add local, because when I open the Tree Share Directory of share and I click on HDA_DATA I read the following error:
Error encountered:
TypeError:message is null

How can I resolve this problem?
Please help me!!!!!!!!!!
Thank you
Roberto

Can you try 'Add path' rather than 'Add local'

I am not a qnap user, but check your permissions.

Ok
i resolve i select with
<?php
$path = '/share/HDA_DATA/Multimedia/';>
in
/share/HDA_DATA/.qpkg/Serviio/web_ui/afb/config.php
thank
