My Question or Issue

I've been trying and failing to delete tracks from a playlist using the API. Every method I attempt results in a 401 error from spotify.

This is a JavaScript Web App and I'm performing both Oauth and delete requests from a Node.js backend.

I have a valid Oauth2 flow and can create/add tracks to playlists on an authorized account.

I am using the passport.js Spotify Strategy to secure an access token and I have defined scopes of 'user-read-email', 'user-read-private', 'playlist-modify-public', 'playlist-modify-private',

Here is the code for my route handler in Node/express:

app.get('/api/playlist/update', requireLogin, async (req, res) => { // * ----- CONFIG ----- (Spotify access token) const config = { headers: { Accept: 'application/json', Authorization: `Bearer ${req.user.accessToken}`, 'Content-Type': 'application/json', }, }; // * ----- GET SNAPSHOT ID OF PLAYLIST ----- const url = `https://api.spotify.com/v1/playlists/${keys.URI_TOP10}`; const response = await axios.get(url, config); const snapshot_id = response.data.snapshot_id; // console.log(snapshot_id); // * get tracks const responseTracks = await axios.get( `https://api.spotify.com/v1/playlists/${keys.URI_TOP10}/tracks`, config ); const tracks = responseTracks.data.items; const trackURIs = tracks.map((track) => { return { uri: track.track.uri }; }); // console.log(trackURIs); // * ----- FORMATE FETCH REQ BODY ----- const body = JSON.stringify({ snapshot_id: snapshot_id, tracks: trackURIs, }); // console.log(body); // * ----- DELETE PLAYLIST TRACKS ----- fetch(`https://api.spotify.com/v1/playlists/${keys.URI_TOP10}/tracks`, { method: 'DELETE', headers: config, body: body, }) .then((response) => { if (response.ok) { console.log( `Tracks successfully deleted from playlist with ID ${keys.URI_TOP10}` ); } else { console.log(response); throw new Error('Error deleting tracks from playlist'); } }) .catch((error) => { console.log(error); }); });
