Perl error accessing Spotify playlists

[gutermhub]

Clicking Spotty->Playlists in web interface produces an empty frame.
The following error is reported in the log file:
Slim::Web::Template::SkinManager::_fillTemplate (346) Error: undef error - Can't call method "playlists" on an undefined value at /var/lib/squeezeboxserver/cache/InstalledPlugins/Plugins/Spotty/OPML.pm line 817.

Logitech Media Server Version: 8.5.3 - 1718684191
Perl Version: 5.34.0 - x86_64-linux-gnu-thread-multi
Spotty v4.10.1

Thank you!

Do you have a player connected to your LMS?

[gutermhub]

3 players connected - 2 Transporters and one Squeezebox Receiver

What web interface are you using? When this happens, would other Spotty menus work? I'm asking because that error should happen if we tried to get the playlist without a player object. But then you shouldn't even get to that menu in the first place...

@peterhadlaw - you gave a thumbs up. Are you seeing the same?

Apologies for a delayed response, I was away from the system.
I am using the default web interface.
All other Spotty menus work just fine.
I updated to 8.5.3 - 1719701725, same behaviour.
I also tried switching between players, turning player on and off - no difference.
