Paypal Button returns 'Order could not be captured'

Question

I am using paypal Buttons SDK. The Code activating the button is:-

        paypal.Buttons({
        createOrder: ( data, actions ) => {
            return actions.order.create({
                purchase_units: [{
                    amount: {
                        value: this.amount.toFixed(2),
                        currency_code: "GBP",
                    }
                }]
            })
        },
        onApprove: ( data, actions ) => {
            return actions.order.capture().then(details => {
              console.log('details',details);
            })
        },
        onError: ( error ) => {
            console.log('error',error);
        }
    }).render('#paypal-button-container')

The User Interface operates as expected, there is then a long pause before the error is returned. The client_id used in the script tag is for a sandbox account. I can find not documentation describing possible cause for the error...

error Error: Order could not be captured

Any advice greatly appreciated.

As suggested in the comment try to do a curl with this URL :

https://www.sandbox.paypal.com/smart/api/order/ODER_ID/capture

And it replies with code 401 and did some research and end up finding that I was using a wrong account to make payments.

I refresh the PayPal login and login with the correct sandbox buyer account and make the payment and It works.

Probably paypal should give correct errors messages.
