Hi everyone im working on JAMMING PROJECT and im stack at step 34!I read lots of forums about this step but somehow i didnt found the fix.
so i got this error “TrackList.js:10 Uncaught TypeError: Cannot read properties of undefined (reading ‘map’)
at TrackList.render (TrackList.js:10:1)
at finishClassComponent (react-dom.development.js:19752:1)”
i get a white screen with this error,and i also commented out the frome Playlist…
That’s perfectly normal at that stage, just ignore it and keep going, it’ll sort itself out at around step 39 
Im at step 54 currently but i still got same error…so i stop i need to fix it somehow…i doble check everything really cant find the problem…
