How fix paypal error with response code 400 - laravel-5

Question

Implementing paypal in my laravel 5.8 app
I got error :
Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/payment/PAYID-NNNNNNNNNN/execute.
My control :
public function paypal_payment_execute()
{
// After Step 1
$apiContext = new \PayPal\Rest\ApiContext(
new \PayPal\Auth\OAuthTokenCredential(
'NNNNN', // ClientID
'NNNNN' // ClientSecret
)
);
$paymentId = request('paymentId');
$PayerID = request('PayerID');
$payment = Payment::get($paymentId, $apiContext);
$execution = new PaymentExecution();
$execution->setPayerId( $PayerID);
$transaction = new Transaction();
$amount = new Amount();
$details = new Details();
$details->setShipping(1.2)
->setTax(1.3)
->setSubtotal(17.50); //
$amount->setCurrency('USD');
$total_sum= 20; // I check this sum is setShipping + setTax + setSubtotal
$amount->setTotal( (integer)$total_sum);
$amount->setDetails($details);
$transaction->setAmount($amount);
$execution->addTransaction( [ $transaction ] ); // !!! I found that here must be an array?
try {
$result = $payment->execute($execution, $apiContext); // Number of error points at this line
} catch (Exception $pce) {
echo '<pre>::'.print_r( json_decode($pce->getData()) );
die("-1 XXZ app/Http/Controllers/PaymentController.php");
}
return $result;
}
I my browse I see output : https://prnt.sc/od3b6v
1) Can somebody say which kind of error is it ?
2) I see lines like :
$this->logger->info
Is it some logging ? Where can I look into it ?
3) That was very strange that error line was shown and not pre output in try catch block:
I expected to see pce->getData output:
} catch (Exception $pce) {
echo '<pre>::'.print_r( json_decode($pce->getData()) );
die("-1 XXZ app/Http/Controllers/PaymentController.php");
}
4) Searching I net I checked that making payment With JS code I set the same total and return urls, like :
<div id="paypal-button"></div>
<script src="https://www.paypalobjects.com/api/checkout.js"></script>
<script>
let total_sum= 20
alert( "-123 total_sum::"+(total_sum) )
paypal.Button.render({
// Configure environment
env: 'sandbox',
client: {
sandbox: 'NNNNN',
production: 'demo_production_client_id'
},
locale: 'en_US',
style: {
size: 'small',
color: 'blue',
shape: 'pill',
},
commit: true,
payment: function(data, actions) {
var payment = actions.payment.create({
"note_to_payer": "Contact us for any questions on your order.",
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
redirect_urls : { //redirect_urls
return_url : '...paypal_payment',
cancel_url : '.../paypal_payment_cancel'
},
transactions: [{
amount: {
total: Number( total_sum ),
currency: 'USD'
}
}]
});
return payment;
},
onAuthorize: function(data, actions) {
return actions.payment.execute().then(function() {
return actions.redirect();
});
}
}, '#paypal-button');
</script>
How fix it ?
composer.json :
"type": "project",
"require": {
"php": "^7.1.3",
...
"laravel/framework": "5.8.*",
"paypal/rest-api-sdk-php": "*",
Modified :
No messages inside of PayPal\Exception\PPConnectionException block anyway.
In your link I noticed that  currency code must be checked.
I created my account about 2 weeks ago : https://prnt.sc/od385x
Where can I check currency code (and maybe country ) ?
Is it in setting for any app ? I did not find where currency can be entered.
if any webhooks must be defoned? What are they for ?
I see “Upgrade to a business account” link . Can it be relative to my problem?
