Could you start with a fresh Gitpod? We made some changes re CORS in the Java backend, and we are surprised that you are still seeing the CORS issue.

A fresh GitPod workspace should have a file named CorsController.java

https://github.com/DataStax-Academy/cassandra-workshop-series/blob/master/week4-AppDev-api/getting-started-with-astra-java/src/main/java/com/datastax/astra/controller/CorsController.java

Thanks so much for your patience. I've not been able to reproduce the CORS issue with this change on my Windows 10 machine.

Please could you test it now ? We cannot reproduce your issues but keep adding logs and countermeasures ad backend and frontend side.


Thank you
