Почему валится Spring WebClient при подписке на него?

Maven:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
            <version>2.1.3.RELEASE</version>
</dependency>
<dependency>
            <groupId>io.projectreactor</groupId>
            <artifactId>reactor-core</artifactId>
            <version>3.2.5.RELEASE</version>
 </dependency>

Java:

WebClient client = WebClient.create("http://localhost:8080");
Mono<Employee> employeeMono = client.get()
                .uri("/employees/{id}", "1")
                .retrieve()
                .bodyToMono(Employee.class);

        employeeMono.subscribe(System.out::println);

Полный код. Пример взят отсюда.
