Playlist Posters Can Not Be Customized By Managed Users

Server Version#: 1.25.3
Player Version#: 4.69.1
Hello,

i have an issues to change the playlist poster with a managed user. It works fine for the admin.
It seems to create an error in the log :
Fil0x7f3888b66b38
MessageError parsing XML: Empty or non-existant file.

Is this about a playlist that managed user created for themselves or a playlist you had shared with them?

it’s about playlist that managed user created for themselves.
