Paypal SDK giving error when trying to create Payment - paypal

Question

I created an app on PayPal with sandbox account. Then i picked up its API Client id and Secret.
I created a new console application and added paypal nuget package version 1.9.1.
internal class Program { static void Main(string[] args) { // Get a reference to the config var config = ConfigManager.Instance.GetProperties();
// Use OAuthTokenCredential to request an access token from PayPal
var accessToken = new OAuthTokenCredential(config["clientId"], config["clientSecret"]);
var apiContext = new APIContext(accessToken.GetAccessToken());
try
{
var payment = new Payment()
{
intent = "authorize",
// A resource representing a Payer that funds a payment. Use the List of `FundingInstrument` and the Payment Method as 'credit_card'
payer = new Payer()
{
// The Payment creation API requires a list of
// FundingInstrument; add the created `FundingInstrument`
// to a List
funding_instruments = new List<FundingInstrument>()
{
// A resource representing a Payeer's funding instrument.
// Use a Payer ID (A unique identifier of the payer generated
// and provided by the facilitator. This is required when
// creating or using a tokenized funding instrument)
// and the `CreditCardDetails`
new FundingInstrument()
{
// A resource representing a credit card that can be used to fund a payment.
credit_card = new CreditCard()
{
billing_address = new Address()
{
city = "Johnstown",
country_code = "US",
line1 = "52 N Main ST",
postal_code = "43210",
state = "OH"
},
cvv2 = "874",
expire_month = 11,
expire_year = 2023,
first_name = "Joe",
last_name = "Shopper",
number = "5105105105105100",
type = "visa"
}
}
},
payment_method = "credit_card"
},
// The Payment creation API requires a list of transactions; add the created `Transaction` to a List
transactions = new List<Transaction>()
{
// A transaction defines the contract of a payment - what is the payment for and who is fulfilling it. Transaction is created with a `Payee` and `Amount` types
new Transaction()
{
// Let's you specify a payment amount.
amount = new Amount()
{
currency = "USD",
// Total must be equal to sum of shipping, tax and subtotal.
total = "107.47",
details = new Details()
{
shipping = "0.03",
subtotal = "107.41",
tax = "0.03"
}
},
description = "This is the payment transaction description."
}
},
payee = new Payee { email = "rassmasood#hotmail.com" }
};
var createdPayment = payment.Create(apiContext);
}
catch (Exception ex)
{
throw;
}
}
}
Using the code above i get the error mentioned below.
{"name":"VALIDATION_ERROR","message":"Invalid request - see details","debug_id":"f3c178cb2a17b","details":[{"field":"/payee","location":"body","issue":"MALFORMED_REQUEST_JSON"}],"links":[]}
is there anything i am doing wrong ?
i tried adding more information to Payee for example its account merchand_id and stuff but didnt worked.
i am expecting the exception to be resolved.

The package you are using is 5 years old and deprecated.
Use the current PayPalCheckoutSDK 1.0.4
