@Test
void createEvent() throws Exception {
    Event event = Event.builder()
                    .name("Spring")
                    .description("Rest Api")
                    .beginEnrollmentDateTime(LocalDateTime.of(2020, 01, 31, 14, 50, 11))
                    .closeEnrollmentDateTime(LocalDateTime.of(2020,2,8, 00,00,00))
            .baseProce(100)
            .maxPrice(200)
            .limitOfEnrollment(100)
            .location("Seoul")
            .build();

    mockMvc.perform(post("/api/events")
                    .contentType(MediaType.APPLICATION_JSON_VALUE)
                    .accept(MediaTypes.HAL_JSON_VALUE)
                    .contentType(objectMapper.writeValueAsString(event)))
            .andDo(print())
            .andExpect(status().isCreated())
            .andExpect(jsonPath("id").exists());
}

@Controller
@RequestMapping(value = "/api/events", produces = MediaTypes.HAL_JSON_VALUE)
public class EventController {
    @PostMapping
    public ResponseEntity createEvent(@RequestBody Event event){
        URI createUri = linkTo(EventController.class).slash("{id}").toUri();
        event.setId(10l);
        return ResponseEntity.created(createUri).body(event);
    }
}

이렇게 실행시 415 에러가 발생하고 있습니다. MediaType을 정상적으로 준 것 같은데 에러가 왜 발생하는지 모르겠습니다.
