Swagger TypeError: Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body

I have added Swagger to my Spring Boot 2 application:

This is my Swagger config:

@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket api() {
    // @formatter:off
    return new Docket(DocumentationType.SWAGGER_2)  
            .select()                                  
            .apis(RequestHandlerSelectors.any())              
            .paths(PathSelectors.any())                          
            .build();
    // @formatter:on
}

}

This is Maven dependency:

    <!-- Swagger2 -->

<dependency>

<groupId>io.springfox</groupId>

<artifactId>springfox-swagger2</artifactId>

<version>2.8.0</version>

</dependency>

<dependency>

<groupId>io.springfox</groupId>

<artifactId>springfox-swagger-ui</artifactId>

<version>2.8.0</version>

</dependency>

When I try to invoke for example http://localhost:8080/api/actuator/auditevents it fails with the following error:

TypeError: Failed to execute ‘fetch’ on ‘Window’: Request with GET/HEAD method cannot have body.

What am I doing wrong and how to fix it ?
