Getting Error : 'Instrument is invalid.'

Dear Sir/madam,
While placing order in node js, I'm getting the error 'Instrument is invalid.'(image attached)
Kindly assist


Code :

function ZerodhaPlaceOrder(OrderFutures) {

    var transaction_type = ''
    if (OrderFutures > 0) {
        transaction_type = "BUY"
    }
    if (OrderFutures < 0) {
        transaction_type = "SELL"
    }
    var PlaceOrder = Math.abs(OrderFutures)
    return new Promise((resolve, reject) => {
        kc.placeOrder("regular", {
            "exchange": "NSE_FO",
            "tradingsymbol": "NIFTY19JUNFUT",
            "transaction_type": transaction_type,
            "quantity": PlaceOrder,
            "product": "NRML",
            "order_type": "MARKET"
        }).then(async function (response) {
            console.log(response);
                order_id = response.data.order_id;
                const1 = await ZerodhaGetOrderStatus(order_id);
                resolve(response);

            })
            .catch(function (error) {
                IsEnteredDecision = 0;
                console.log(error);
                reject(error);

            });
    });

}
