Caused by: org.eclipse.jgit.api.errors.RefNotFoundException: Ref master cannot be resolved


I'm working on Spring Boot 2.4.2.RELEASE and developing config-server for my microservices project. Below is the my code which I develop so far.

ConfigServerApplication.java

@SpringBootApplication
@EnableConfigServer
@EnableEurekaClient
public class ConfigServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigServerApplication.class, args);
    }
}

application.properties

spring.application.name=config-server

server.port=9296

spring.cloud.config.server.git.uri=https://github.com/shabbirdwd53/config-server
spring.cloud.config.server.git.clone-on-start=true
