Spring Boot don't call my custom HttpMessageConverter

Question

I am implementing a HttpMessageConverter and when I invoke the endpoint Spring Boot call AbstractJackson2HttpMessageConverter instead mine.

I am using Spring Boot 2.7.6.

The endpoint:

public DocumentId createDocument(List<File> files)

The WebConfig according with Spring Documentation (I can confirm that Spring run this method):

@Configuration(proxyBeanMethods = false)
public class WebConfig {

    @Bean
    public HttpMessageConverters customConverters() {
        HttpMessageConverter<?> additional = new FileHttpMessageConverter();
        return new HttpMessageConverters(additional);
    }
}

The HttpMessageConverter:

@Component
public final class FileHttpMessageConverter extends AbstractHttpMessageConverter<File> {

I already changed the AbstractHttpMessageConverter type to Collection<File> and doesn't work too.

Any idea what I might be doing wrong?

Thanks in advance.
