Get a Playlist endpoint returns empty object

[AverageUnknown]

I am attempting to use the Get a Playlist endpoint but it keeps returning an empty object {}. I thought this might be an issue with how I formatted my request, so I went to verify by using the web console page for this endpoint. However, even with the sample data supplied in the web console, the response still appears to be an empty object (see attachment). The status code is 200 so this doesn't seem to be an issue of authorization or access privileges. Why is this happening and how can I get the result I'm looking for?

The "fields" parameter should be "tracks.items(added_by.id,track(name,href,album(name,href)))". "items" is not a top-level key in the JSON payload.

Fantastic, thanks. Very confusing that the sample data is invalid.
