Hi, we are working on a web project with react.js + spring boot, we use oauth2 and azure-active-directory-spring-boot-starter library to authenticate users, we set it up by following the tutorial: https://learn.microsoft.com/en-us/java/api/overview/azure/spring-boot-starter-active-directory-readme?view=azure-java-stable. It works fine locally, however it gives a CORS error after deploying it on server, if we disable the CORS on browser, it returns a login html file instead of an id token after logging in, i81663-localhost-return.jpgs it caused by azure ad's endpoint? If so is there any way to solve this issue? Thank you so much!81609-cors-message.png81691-deployment-return.jpg
