Getting 405 Request method not allowed

Hi Team,
I was trying to place a BUY order for an option using the below attributes, I am getting 405 error code with message : Request method not allowed
Order params : {
"exchange" : "NFO",
"tradingsymbol" : "NIFTY2420121700CE",
"transactionType" : "BUY",
"quantity" : 50,
"price" : 222.0,
"product" : "MIS",
"orderType" : "MARKET",
"validity" : "DAY",
"disclosedQuantity" : null,
"triggerPrice" : null,
"squareoff" : null,
"stoploss" : null,
"trailingStoploss" : null,
"tag" : "TEST_NFO_TAG",
"parentOrderId" : null,
"validityTTL" : 0,
"icebergQuantity" : 0,
"icebergLegs" : 0,

}

Could you please check what is wrong here. I am using kiteconnect version: 3.3.2 in my java application
