Helloworldless,

We used ServerOAuth2AuthorizedClientExchangeFilterFunction and could not get the OAuth refresh token working. So we switched to ServletOAuth2AuthorizedClientExchangeFilterFunction based on your code. I am just wondering why we need to use ServletOAuth2AuthorizedClientExchangeFilterFunction?

The "Server" one is the reactive version. "Servlet" is the traditional, non-reactive one.

For reference:

• Reactive: https://docs.spring.io/spring-security/site/docs/5.4.2/reference/html5/#webclient-setup
• Servlet: https://docs.spring.io/spring-security/site/docs/5.4.2/reference/html5/#oauth2Client-webclient-servlet

Thanks. I did use Reactive setup and somehow ServerOAuth2AuthorizedClientExchangeFilterFunction does not work for us. So we had to switch to Servlet setup.
