Urlencode error using smartplaylist plugin

Tried switching on urlencode to make the plugins smartplaylists and beetstream work together. Currently my playlists don't work and every song can't be played.

Error when using splupdate:

smartplaylist: Updating 1 smart playlists...
smartplaylist: Creating playlist all.m3u

Rather new to both linux and beets, and advice is appreciated. Using most recent version of endeavourOS and KDE.

Start in beetsplug/smartplaylist.py at the update_playlists path shown in the traceback, then reproduce the issue with splupdate and urlencode: yes. Done means the command no longer raises the quoted TypeError and the generated smart playlist can be used to play its songs.
