Jamming project Uncaught TypeError: Cannot read properties of undefined (reading 'map')

Step 34 states:

In the TrackList component, use the .map() method to render each track in the tracks property

So the error occurs in the TrackList component – not the Track component that you posted here.

The Tracklist component is rendered twice:

  1. In the PlayList Component
  2. In the SearchResults Component

Do you pass the tracks to both rendered TrackList components?
