Smart Playlist disappearing

[KaoriRinaFujimoto]

Hi all,

i've created a Smart Playlist that lists all liked songs with this expression: (essentially the example from the documentation here, but I've added the missing comma after the operator definition).

{"type": "sticker", "sticker": "like", "value": "2", "op": "=", "sort": "", "sortdesc": false, "maxentries": 200}

the m3u playlist is being generated and can be found in the playlists directory under /var/lib/mpd/playlists - but for some reason the smart playlist disappears from /var/lib/mympdos/smartpls - so there is no way to regenerate the smart playlist.

I've created a couple more smart playlists manually and all of them are working fine, only this one is causing issues.

Does anyone know what I might be doing wrong here? The json syntax looks fine to me.
Thank you!

Ok I think I've figured out the issue: the value for the sort key should not be empty.
The log is even pointing that out Dec 3 10:36:31 myMPDos daemon.err mympd: Invalid sort tag: (should have checked earlier :/ )

After updating the expression to this:

{"type": "sticker", "sticker": "like", "value": "2", "op": "=", "sort": "Album", "sortdesc": false, "maxentries": 200}

it's working now.
