Information

Thank you for your great work.

I tried using your tool to authenticate with Spotify. But that wasn't possible out of the box, so I had to make the following adjustments:

cache-control header

If the cache-control header is sent with the token queries, the server returns a CORS error. Solution => a disableCacheControlHeader flag in OAuth2AuthenticateBaseOptions

Authorization required for token queries

Spotify would like to have an authorization for the queries for the access_token and refresh_token in the header (https://developer.spotify.com/documentation/general/guides/authorization/code-flow/)

Authorization: Basic base64encodedKey The key consists of Spotify Client ID and Client Secret

solution => Quick and dirty: also send the additionalResourceHeaders with the token queries clean: own property for additionalTokenRequestHeaders

This issue is still present and it prevents using this with Keycloak + code grant.
