"api Request Failed" when using cashfree in react native

I am trying to use cashfree in my react native app for payment.

Below is my code:

import {  CFPaymentGatewayService,  CFErrorResponse,} from 'react-native-cashfree-pg-sdk';import {  CFDropCheckoutPayment,  CFEnvironment,  CFPaymentComponentBuilder,  CFPaymentModes,  CFSession,  CFThemeBuilder,} from 'cashfree-pg-api-contract';export default function PaymentComponent() {  const SANDBOX_ENVIRONMENT = CFEnvironment.SANDBOX;  useEffect(() => {    console.log('MOUNTED');    CFPaymentGatewayService.eventSubscriber = {      onReceivedEvent(eventName: string, map: Map<string, string>): void {        console.log('Event recieved on screen: '+            eventName +' map: '+            JSON.stringify(map),        );      },    };    CFPaymentGatewayService.setCallback({      onVerify(orderID: string): void {        console.log('orderId is :'+ orderID);      },      onError(error: CFErrorResponse, orderID: string): void {        console.log('exception is : '+            JSON.stringify(error) +'\norderId is :'+            orderID,        );      },    });    return () => {      console.log('UNMOUNTED');      CFPaymentGatewayService.removeCallback();      CFPaymentGatewayService.eventSubscriber = {        onReceivedEvent(eventName: string, map: Map<string, string>): void {          console.log(            `Event received on screen: ${eventName} with map: ${JSON.stringify(              map,            )}`,          );        },      };    };  }, []);  const startCheckout = useCallback(async () => {    try {      const session = new CFSession(        session_id,        order_id,        CFEnvironment.SANDBOX,      );      const paymentModes = new CFPaymentComponentBuilder()        .add(CFPaymentModes.CARD)        .add(CFPaymentModes.UPI)        .add(CFPaymentModes.NB)        .add(CFPaymentModes.WALLET)        .add(CFPaymentModes.PAY_LATER)        .build();      const theme = new CFThemeBuilder()        .setNavigationBarBackgroundColor('#E64A19')        .setNavigationBarTextColor('#FFFFFF')        .setButtonBackgroundColor('#FFC107')        .setButtonTextColor('#FFFFFF')        .setPrimaryTextColor('#212121')        .setSecondaryTextColor('#757575')        .build();      const dropPayment = new CFDropCheckoutPayment(        session,        paymentModes,        theme,      );      CFPaymentGatewayService.doPayment(dropPayment);    } catch (e: any) {      console.log(e.message);    }  }, []);}

On click on button, cashfree payment screen is coming, but after doing payment I am getting error:

exception is : {"status":"FAILED","message":"api Request Failed","code":"request_failed","type":"api_error"}orderId is :021ff160-f4b0-493a-aa46-23596ee686e3 LOG  reason: "{\"error\":\"{\\\"status\\\":\\\"FAILED\\\",\\\"message\\\":\\\"api Request Failed\\\",\\\"code\\\":\\\"request_failed\\\",\\\"type\\\":\\\"api_error\\\"}\",\"orderID\":\"021ff160-f4b0-493a-aa46-23596ee686e3\"}" LOG  errorString :{"status":"FAILED","message":"api Request Failed","code":"request_failed","type":"api_error"} LOG  errorStringObject :[object Object] LOG  exception is : {"status":"FAILED","message":"api Request Failed","code":"request_failed","type":"api_error"}orderId is :021ff160-f4b0-493a-aa46-23596ee686e3

startCheckout is called on click of button.

I am not sure why this error is coming, as I have followed cashfree documents and did as it is mentioned in it
