Can't find the data items

[RobertJanVlak]

When i try to run the code i get the following error:
"TypeError: Cannot read property 'item' of undefined"

It's about this piece of code:
success: data => { this.setState({ item: data.item, is_playing: data.is_playing, progress_ms: data.progress_ms });

So all the steps are working perfect. I get the autentication screen from spotify, and the moment i click accept i get this error and i can't seem to find the solution for it.

You need to be listening to something on your Spotify account so that this error does not occur. I will be sending an update.

Confirmed that this is indeed the issue - does someone want to put in better error handling incase you are not listening to music?

Same error but i don't know how to fix it.
