Bubble.io Spotify API has stopped working

Hi,

I have a Bubble.io application which has Spotify API integration (using Pathfix to handle the OAuth).

I've not worked on this app for many months and since then the API calls have stopped working.

As it's been a while since I done this I can't now remember how I got it working - I suspect either a token has expired or perhaps my Pathfix account needs fixing.

I could troubleshoot this and fix it, but I'm self taught and relatively new to API integrations so I think an experienced developer will get me to the problem a lot faster, so I'm looking for someone with experience of Bubble.io, Pathfix and Spotify API - or just a good understanding of troubleshooting API calls.

Thanks,
Rob
