PayPal Laravel 8 integration using srmklive error - php

Question

I want to integrate PayPal into my Laravel website but I'm getting this error:
Argument 1 passed to Symfony\Component\HttpFoundation\RedirectResponse::__construct() must be of the type string, null given, called in C:\xampp\htdocs\Delta\vendor\laravel\framework\src\Illuminate\Routing\Redirector.php on line 233
Controller File
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Srmklive\PayPal\Services\ExpressCheckout;
class PayPalController extends Controller {
public function __construct() {
$this->provider = new ExpressCheckout();
}
public function payment() {
$data = [];
$data['items'] = [
[
'name' => 'codechief.org',
'price' => 100,
'desc' => 'Description goes herem',
'qty' => 1
]
];
$data['invoice_id'] = 1;
$data['invoice_description'] = "Order #{$data['invoice_id']} Invoice";
$data['return_url'] = route('payment.success');
$data['cancel_url'] = route('payment.cancel');
$data['total'] = 100;
$provider = new ExpressCheckout;
$response = $provider->setExpressCheckout($data);
$response = $provider->setExpressCheckout($data, true);
return redirect()->away($response['paypal_link']);
}
Please give me a solution!

Answer 1

Actually, your problem is that $response['paypal_link'] isn't returning a link. Replace line:
return redirect()->away($response['paypal_link']);
With the code below:
if($response['paypal_link'] == null){
// custom redirection
return redirect()->back()->with(['error'=>'paypal link no set'])
}
return redirect()->away($response['paypal_link']);
