Inconsistent API Behavior, sometimes orders are rejected as if it's an InputException

Minimum reproducible sample

const KiteConnect = require("kiteconnect").KiteConnect;

const kite = new KiteConnect({
  api_key: "xxx",
  access_token: "xxx"
})

const order = {
  "variety": "regular",
  "exchange": "NSE",
  "tradingsymbol": "ORIENTELEC",
  "transaction_type": "BUY",
  "quantity": 20,
  "product": "MIS",
  "order_type": "LIMIT",
  "price": 383.5,
  "validity": "DAY",
  "disclosed_quantity": null,
  "trigger_price": null,
  "squareoff": null,
  "stoploss": null,
  "trailing_stoploss": null,
  "tag": "FC_LONGENTRY",
  "order_id": null
};

(async ()=>{
  try {
    const resp = await kite.placeOrder(order.variety, order)
    console.log(resp)
  } 
  catch(err) {
    console.log(err)
  }
})();

As you see, sometimes orders go through, and sometimes they don't.
The order payload is definitely the same.

something very fishy happening inside Zerodha servers.

try {
    const order = await kc.placeOrder('regular', {
        exchange:'NSE',
        tradingsymbol:'ORIENTELEC',
        quantity:20,
        product:'MIS',
        order_type:'LIMIT',
        price: 383.5,
        validity:'DAY',
        transaction_type:'BUY',
        tag: "FC_LONGENTRY",
        disclosed_quantity: null,
        trigger_price: null,
        squareoff: null,
        stoploss: null,
        trailing_stoploss: null,
        order_id: null
    });
    console.log(order); }
    catch(err) {
        console.log(err)
    }

I just tried the same order param at my end for the node client. It's working perfectly fine.

@rakeshr it's failing "Sometimes"
Try running it in a loop 10 times.

Did you check the exception type and message in the json response?
