Invalid bean definition with name 'configServicePropertySource'

Question

I have defined ConfigServicePropertySourceLocator bean like following

@Primary
@Bean
public ConfigServicePropertySourceLocator configServicePropertySource(
        ConfigClientProperties configClientProperties) {
    ConfigServicePropertySourceLocator sourceLocator = new ConfigServicePropertySourceLocator(
            configClientProperties);
    sourceLocator.setRestTemplate(clientOnlyRestTemplate());
    return sourceLocator;
}

but i get the following exception (This is how it is printed in docker) although my bean is marked as @Primary

WARN 1 --- [           main] s.c.a.AnnotationConfigApplicationContext : Exception encountered during context initialization - cancelling refresh attempt:
