React native – PhonePe React-native Sdk Custom UPI Open Intent (Android) returns Status as "Failure" all the time

React-Native Phonepe SDK used for Phonepe integration if I pass base64 response and shasha256 hash key for SDK to PhonePe Custom UPI Open Intent it always gives {"error": "Transaction Interrupted!", "status": "FAILURE"} error but if try standard checkout(asking the user to enter UPI id and payment request) everything works fine.

custom up intent api docs I tried with passing the same values in API it works fine it returns redirect url but in sdk it throws error
