SpringBoot ObjectMapper don't convert bean object

This code goal

I try to reqeust some api using RestTemplate

Now I used that

RestTemplate and normal ObjectMapper (not custom object)

I call this procedure

@Configuration
@ConfigurationProperties(prefix = "***********")
@Getter
@Setter
@ToString
public class RequestBody {

    @JsonProperty("allFetched")
    private Boolean enableAllFetched;
    private String resultType;
    private List<String> owners;
    private List<String> statuses;

    public RequestBody() {
    }

    public RequestBody(Boolean enableAllFetched, String resultType, List<String> owners, List<String> statuses) {
        this.enableAllFetched = enableAllFetched;
        this.resultType = resultType;
        this.owners = owners;
        this.statuses = statuses;
    }
}


HttpEntity<RequestBody> requestBodyHttpEntity = new HttpEntity<>(requestBody);
restTemplate.exchange(properties.getUri(), HttpMethod.POST, requestBodyHttpEntity, ReponseDto.class, params);

I get below error detail explaination.

org.springframework.http.converter.HttpMessageConversionException: Type definition error: [simple type, class org.springframework.context.expression.StandardBeanExpressionResolver]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class org.springframework.context.expression.StandardBeanExpressionResolver and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: ****.***RequestBody$$EnhancerBySpringCGLIB$$16ef92cb["$$beanFactory"]->org.springframework.beans.factory.support.DefaultListableBeanFactory["beanExpressionResolver"])

When I make new RequestBody object, this logic worked. But, I used to this RequestBody bean object, I always get the upper message. How can I do?
