Spring Cloud Openfeign JSON parse error: java.time.format.DateTimeParseException [Spring Boot - Feign Client]

When I make a request to a service containing java.util.Date with FeignClient, I get this error: org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: java.time.format.DateTimeParseException: Text '1692738000000' could not be parsed at index 0

My dto:

public class InputDto {
    private Date startDate;
    private Date endDate;
}

FeignClient service:

@PostMapping(value = {"/searchFile"}, produces = {MediaType.APPLICATION_JSON_VALUE})
ResponseEntity<ServiceResponse<List<FileDto>>> searchFile(@RequestBody InputDto searchDto);

<spring-boot.version>2.7.4</spring-boot.version>
<spring-cloud-starter-openfeign.version>3.1.5</spring-cloud-starter-openfeign.version>

If I define my variables as java.time.LocalDate I don't get an error. why does this problem occur?
