Property configuration of OPA endpoint combined with OPA service not working as it was planned, value does not inject to the service, and during runtime, a NullPointer exception will occur when Storage tries to send request OPA endpoint. And it no follow best practices as it said that configuration should be clean POJO objects. https://www.baeldung.com/configuration-properties-in-spring-boot#simple-properties
Property injects as it should be, via property file or via env variable.
This is a minor fix that will not require any changes in CSP configurations.
