Error in Order Placement: {'code': -50, 'message': 'Invalid input', 's': 'error'}

Hi Team,

I wrote a naive code to place order using V3 Python package of Fyers as below:

for index, row in new_orders.iterrows():
                qty = int(approx_margin_per_order/float(row['Entry-Price']))
                if row['Decision'] == "Buy":
                    side = 1
                else:
                    side = -1
                
                order = {
                    "symbol": "NSE:"+row['Symbol']+"-EQ",
                    "qty": qty,
                    "type":1,
                    "side":side,
                    "productType": "BO",
                    "limitPrice": row['Entry-Price'],
                    "stopPrice": row['Trigger-Price'],
                    "validity": "DAY",
                    "disclosedQty": qty,
                    "offlineOrder": False,
                    "stopLoss": row['Stoploss'],
                    "takeProfit": row['Target']
                }
                print(order)
                try:
                    order_response = fyers.place_order(order)
                    print(order_response)
                except:
                    logger.error("Error in placing order")

However, I am getting below error in my logs, can anyone diagnose?

{'symbol': 'NSE:IRCON-EQ', 'qty': 6, 'type': 1, 'side': 1, 'productType': 'BO', 'limitPrice': '155.35', 'stopPrice': '155.3', 'validity': 'DAY', 'disclosedQty': 6, 'offlineOrder': False, 'stopLoss': '137.45', 'takeProfit': '185.5'}
{'code': -50, 'message': 'Invalid input', 's': 'error'}
{'symbol': 'NSE:ITI-EQ', 'qty': 3, 'type': 1, 'side': 1, 'productType': 'BO', 'limitPrice': '272.45', 'stopPrice': '272.4', 'validity': 'DAY', 'disclosedQty': 3, 'offlineOrder': False, 'stopLoss': '223.75', 'takeProfit': '325.3'}
{'code': -50, 'message': 'Invalid input', 's': 'error'}

For all orders in my pandas dataframe, I am getting same error.
