I'm setting up a Booking router in NodeJS, and I have many params in.
Now when I forgot params I return an error like : 

500: Need more information

I wonder if it's possible to know which params are missing when I return the error code.

This is for a new API made in NodeJS

Here are the params that I want to retrieve from the front ( made in ReactJS )

```
let body = {
        agentDutyCode: "STRING",
        RatePlanCode: params.rateCode,
        RoomCode: params.roomCode,
        AmountAfterTax: params.amountTax,
        Start: params.fromDate,
        End: params.toDate,
        CardCode: params.cardCode,
        CardNumber: params.cardNumber,
        ExpireDate: params.expireDate,
        SeriesCode: params.cvv,
        CardHolderName: params.nameCard,
        ChainCode: params.chainCode,
        HotelCode: params.hotelCode,
        RoomQuantities: params.roomQuantities,
        GuestQuantitie: params.numberGuest,
        GuestPerRoom: params.guestPerRoom,
        LastName: params.lastName,
        FirstName: params.firstName,
        PhoneNumber: params.phoneNumber,
        email: params.email,
        FVL_SUBUNIT_7: params.walletAddress
    }

```

And this is my promise :

```js
 cdsJson.bookResource(req.body)
        .then((response) => {
            if (response !== null) {
                res.response = {
                    ...response
                }
            } if (response.hotel.length === 0) {
                res.respStatus = 500
                res.response = {
                    sendMsg: "Need more informations"
                }
                next('route')
            }
            return response
        })

```

If the request succeeds I got a reservation ID otherwise I got :

Error 500: Need more information
