Answer 1

The multipart/mixed for spring webflux(2.1.0) did not work for me. Here is an alternative approach that worked

• Working - spring-boot-starter-web/Multipart[] - upload files where one is the payload, another is a file itself. In my case since the payload was constant, it worked.
• Not working - spring-boot-starter-webflux/Flux. The flux is empty. I tried this https://github.com/spring-projects/spring-boot/issues/13268, but it didn't work
