Создаю backend на node.js, express.js + mongodb (облачное подключение).
При запросе на создание новой записи через Postman (post запрос на
localhost:5000/api/certificate) появляются только автоматические поля "_id" и "__v", а указанные мною поля не создаются (получается добавить только если задавать значение default, в таком случае появится значение).
В чем может быть причина?

const config = require("config");

const PORT = config.get("port") || 5000;
const URI = config.get("mongoUri");
//middlewares
app.use(cors());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
//routes prefix
app.use("/api/certificate", require("./routes/routes"));
async function start() {
try {
//connect to database
await mongoose
.connect(URI, {
useNewUrlParser: true,
useUnifiedTopology: true,
})
.then(() => console.log("Connecting to the database!"))
.catch((err) => console.log(err));
// start server
app.listen(PORT, () =>
console.log(`App has been started on port ${PORT}...`)
