findadd/searchadd not functioning, mppopmd reporting invalid utf-8 sequence

[khaytsus]

I can't get findadd or searchadd to work and I'm seeing an error in the verbose logs when I try to do so. Installed on Fedora 38 using cargo install mpdpopm

Server is running

mppopmd -c /home/wally/.config/mppopmd/config -d -F

Config file (to match my sticker database tags that are already populated)

((log . "/home/wally/.config/mppopmd/mppopmd.log")
 (host . "192.168.0.7")
 (port . 6600)
 (local_music_dir . "/var/lib/mpd/music")
 (playcount_sticker . "playCount")
 (lastplayed_sticker . "lastPlayed")
 (played_thresh . 0.6)
 (poll_interval_ms . 5000)
 (commands_chan . "unwoundstack.com:commands")
 (rating_sticker . "rating"))

get-rating seems to work fine

mppopm -v -c /home/wally/.config/mppopmd/config  get-rating 
Connected 0.23.5.
Sent message `sticker get song "Rock/Evanescence/Fallen/11 Evanescence - Fallen - 11 - Whisper.mp3" rating'; got `sticker: rating=6
OK
'
6

But findadd does not (rating value does not matter here, 1, 5, 6, etc, should have really used >5 in this example to match above, just FYI)

mppopm -v -c /home/wally/.config/mppopmd/config findadd "(rating > 6)"

Connected 0.23.5.
findadd: got ``(rating > 6)'', quoted to ``"(rating > 6)"''.
Sent `sendmessage unwoundstack.com:commands "findadd \"(rating > 6)\""'; got `OK
'.
