Code to make Token

- (IBAction)save:(id)sender
{
STPCard *card = [[STPCard alloc] init];
card.number = self.paymentView.card.number;
card.expMonth = self.paymentView.card.expMonth;
card.expYear = self.paymentView.card.expYear;
card.cvc = self.paymentView.card.cvc;
[[STPAPIClient sharedClient] createTokenWithCard:card
                                      completion:^(STPToken *token, NSError *error) {
                                          if (error) {
                                              NSLog(@"%@",error);
                                          } else {
                                              NSString *myVal = [NSString stringWithFormat:@"%@",token];
                                              NSLog(@"%@",token);
                                              [PFCloud callFunctionInBackground:@"chargeMoney"
                                                                 withParameters:@{@"token":myVal}
                                                                          block:^(NSString *result, NSError *error) {
                                                                              if (!error) {
                                                                                  NSLog(@"from Cloud Code: %@",result);
                                                                              }
                                                                          }];

                                          };
                                      }];


}

Code to Charge

Parse.Cloud.define("chargeMoney", function(request, response) {
  response.success(request.params.token);
var stripe = require('stripe');
stripe.initialize('sk_test_ldqwdqwdqwdqwdwqdqwd ');

var stripeToken = request.params.token;

  var charge = stripe.charges.create({
  amount: 1000, // amount in cents, again
  currency: "usd",
   source: stripeToken,
  description: "[email protected]"
}, function(err, charge) {
  if (err && err.type === 'StripeCardError') {
    // The card has been declined
 }
   });

});

Error Ich bekomme

  [Error]: TypeError: Cannot call method 'create' of undefined
