this doesn't work:

 ServiceApiResponse nileResponse = restNile().apiSmarttvStreamLiveV5NcsServiceId(ncsServiceId, xAccountId, xMso,null, ip, null, null, null, null, null, null)
                .post(requestBody.toString().getBytes());


this works:

        ServiceApiResponse response = restIPVS().apiSmarttvUserCapabilitiesV3(account, mso, null, null, null, ip).get();
        ResponseData.setResponse("apiSmarttvUserCapabilitiesV3", Objects.requireNonNull(response.json()));


error message:

java: incompatible types: sth.template.rest.TemplateResponse cannot be converted to sth.ServiceApiResponse
