The interface did not clearly indicate an error, so I had to target the pom configuration file first. As expected, it was a POM configuration problem

The error introduced here should correctly be

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
