Since the fix of this issue : https://github.com/spring-cloud/spring-cloud-config/issues/1771, I experience a NullpointerException at the launch of my service. Indeed, the "location" var is null in my case. Note : since the new Config file processing in Spring Boot 2.4, I'm using the Legacy Processing (spring.config.use-legacy-processing: true), migrating in the new process is way too breaking for my project.
