Upi payment is not working in android app

I am using implementation 'com.shreyaspatil:EasyUpiPayment:2.2' for upi payment. But gpay fails the trasaction saying the transaction might be risky . PhonPe says transaction failed due to technical errors. I dont understand what is the problem , here is the code

final EasyUpiPayment easyUpiPayment = new EasyUpiPayment.Builder()
                    .with(this)
                    .setPayeeVpa("xxxxxxxxxxxxxxx")
                    .setPayeeName("xxx xxxx  xxxx")
                    .setTransactionId(transactionId)
                    .setTransactionRefId("Ref" + transactionId)
                    .setDescription(description)
                    .setAmount(amount)
                    .build();

            easyUpiPayment.startPayment();
