HttpMediaTypeNotAcceptableException на контроллере Spring Boot Rest для загрузки файла csv

У меня есть приложение Spring Boot с методом в RestController для загрузки файла csv и тестом для проверки случая, когда возникает исключение. Когда я выполняю свой тест, я получаю эту ошибку в ExceptionHandler: HttpMediaTypeNotAcceptableException: не удалось найти приемлемое представление

Я пытаюсь добавить принятие обоих APPLICATION_JSON_VALUE, TEXT_PLAIN_VALUE в запрос теста, но получаю ту же ошибку.

@RestController
@RequestMapping(value = "/users/files", produces = MediaType.APPLICATION_JSON_VALUE)
@Slf4j
@RequiredArgsConstructor
public class UserFilesController {

... 

    @GetMapping(value = "/{id}/reports", produces = MediaType.TEXT_PLAIN_VALUE)
    public ResponseEntity<ByteArrayResource> exportReportById(@PathVariable long id, HttpServletResponse response)
            throws UserFileLoaderException, IOException {
        HttpHeaders headers = new HttpHeaders();
        headers.add(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + REPORT_EXPORT_FILE_NAME + "\"");
        headers.add(HttpHeaders.CONTENT_TYPE, MediaType.TEXT_PLAIN_VALUE);
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        try (Writer writer = new OutputStreamWriter(out)) {
            userFilesService.exportReport(id, writer);
            return ResponseEntity
                    .ok()
                    .headers(headers)
                    .body(new ByteArrayResource(out.toByteArray()));
        }
    }

    @ExceptionHandler({UserFileLoaderException.class, IOException.class, Exception.class})
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public ResponseEntity<ErrorResponse> handleInternalErrorException(HttpServletRequest request, Exception e) {
        log.error("Unexpected error: {}", e.getMessage());
        ErrorResponse response = ErrorResponse.builder().errorMessage(e.getMessage()).build();
        return new ResponseEntity<>(response, HttpStatus.INTERNAL_SERVER_ERROR);
    }

...

}

@Test
void exportReportByIdUserFileLoaderException() throws Exception {
    doThrow(UserFileLoaderException.class).when(userFilesService).exportReport(eq(1L), any(Writer.class));
    mockMvc.perform(get(URL + "/{id}/reports", 1L)
                            .queryParam("format", "text")
                            .contentType(APPLICATION_JSON_VALUE))
           .andExpect(status().isInternalServerError());
    verify(userFilesService).exportReport(eq(1L), any(OutputStreamWriter.class));

Я решил это, добавив

MediaType.APPLICATION_JSON_VALUE

для «производства» тега в контроллере и удаления

.queryParam(формат, текст)

из тестов вот так:

@GetMapping(value = "/{id}/reports", produces = {MediaType.TEXT_PLAIN_VALUE, MediaType.APPLICATION_JSON_VALUE})

@Test
void exportReportByIdUserFileLoaderException() throws Exception {
    doThrow(UserFileLoaderException.class).when(userFilesService).exportReport(eq(1L), any(Writer.class));
    mockMvc.perform(get(URL + "/{id}/reports", 1L)                            
                            .contentType(APPLICATION_JSON_VALUE))
           .andExpect(status().isInternalServerError());
    verify(userFilesService).exportReport(eq(1L), any(OutputStreamWriter.class));
}
