Hi there!
I'm trying to connect Dropbox via FileStack to upload files.
They have some recomendation for that - https://www.filestack.com/docs/uploads/storage/#dropbox
I created and configured the app as described in the recommendations.
I try to save the token on their side, but I get the following error.


I can't figure out where the problem is, on your side or on the FileStack side?
