Integration to paypal at local server

In laravel 5.8 app I make integration to paypal with paypal/rest-api-sdk-php and I make as :

                            // Set up a payment
                            payment: function(data, actions) {
                                return actions.payment.create({

                                    return_urls : {
                                        return_url : 'http://local-votes.com/paypal_payment'
                                    },

                                    transactions: [{
                                        amount: {
                                            total: '0.01',
                                            currency: 'USD'
                                        }
                                    }]
                                });
                            },
                            // Execute the payment

if return_urls is uncomment I got error in console :

if to comment return_urls payment works ok but I do not have payment retun action. If there is a way to work with it locally. Looking at some example code, looks like that is possible...
