I am working on a Spring Boot application for a real estate listing. I have implemented functionality to upload images when adding or editing listings. The image upload works when adding a new listing, but it doesn’t work when editing an existing listing.

I am running a Spring Boot application using Gradle. I checked the version of my project using JDK 11. Incoming connections to other tools are also completely fine. But I get error like below.

So I am making a new API that sends UUIDs from the application through Email when you Sign-up.

I’m trying to run a web app using Springboot (Java Gradle) but it keeps failing when building.
