Hi, i wrote a code like this for Paytm, when i click on button it will call the PayNow function, the PayNow function will open the popup and it shows this error "404 Not Found".
Here is my code.
generateOrderId() {
let cid = "";
let possible = "0123456789";
for (var i=0; i < 8; i++) {
cid += possible.charAt(Math.floor(Math.random() * possible.length));
}
return cid;
}
var order_id = this.generateOrderId();
var cust_id = this.generateOrderId();

PayNow() {
const details = {
generationUrl: "https://gym.index-i.com/generate_checksum", //working fine
validationUrl: "https://gym.index-i.com/verify_checksum", //working fine
mode:'Staging',

orderId: order_id,
email: 'ajay402sjbit@gmail.com',
phone: '9741104021',
custId: cust_id,
checksumhash: resp.data.CHECKSUMHASH, // generating from server side
callback: "https://securegw-stage.paytm.in/theia/paytmCallback?ORDER_ID="+order_id
};
paytm.startPayment(details)
}

How to solve this error, any help is Appreciated.
