Как исправить: отсутствует обязательное тело запроса: [org.springframework.http.converter.HttpMessageNotReadableException:]

Я обновляю логический столбец в своей базе данных для утверждения учетных записей клиентов с помощью угловой кнопки внешнего интерфейса. Как только я отправляю свой запрос, мой контроллер выдает ошибку Resolved [org.springframework.http.converter.HttpMessageNotReadableException:Required request body is missing:. Пытались отладить его и были бы признательны за некоторые рекомендации по этому поводу.

Мой код пока выглядит следующим образом:

контроллер:

@RequestMapping(value = "/customers/afisapprove", method = 
RequestMethod.POST)
public ResponseEntity<?> updCustAfisStatus(@RequestBody Customer 
customer) throws Exception {
    try {
        System.out.println("account no##" + 
customer.getAccountNumber());
        System.out.println("afis no##" + 
customer.getAfisStatus());
        System.out.println("afis id##" + customer.getId());

        int approveCust = 
customerService.approveAfisCustomer(customer.isActive());

        // begin saving audit trail
        auditTrail = new AuditTrail((customer.getCreatedBy()), "Approved Customer " + customer.getFullName(), date,
                "Approve Customer");
        auditTrailService.saveAuditTrail(auditTrail);
        System.out.println("approved##" + approveCust);
        if (approveCust > 0) {
            // int trash = customerService.trashAfisBio(customer.getId());
            // if (trash <= 0 ) {
            // return new ResponseEntity<>(new CustomResponse(CustomResponse.APIV,
            // 200,false,
            // "failed to trash raw images"),HttpStatus.OK);
            // }
            return new ResponseEntity<>(
                    new CustomResponse(CustomResponse.APIV, 200, true, "customer approved successfully"),
                    HttpStatus.OK);

        }
        return new ResponseEntity<>(
                new CustomResponse(CustomResponse.APIV, 200, false, "failed to approve customer"), HttpStatus.OK);
    } catch (Exception e) {
        return new ResponseEntity<>(
                new CustomResponse(CustomResponse.APIV, 200, false, "Server error processing request"),
                HttpStatus.OK);
    }

Я действительно не знаю, что я делаю неправильно. Как я могу это исправить и понять причину ошибки?
