Error when calling capture method

[tsdevelopment]

When I install the bundle with a fresh Symfony 5.2 installation I got the following error:

Attempted to load class "MergeQuery" from namespace "League\Uri\Modifiers".
Did you forget a "use" statement for another namespace?

My configuration:

payum:
    storages:
        App\Entity\Payment: { doctrine: orm }

    security:
        token_storage:
            App\Entity\PaymentToken: { doctrine: orm }

    gateways:
        paypal_express_checkout:
            factory: paypal_express_checkout
            username: ****
            password: ****
            signature: ****

<?php

namespace App\Controller;

use App\Entity\Payment;
use Payum\Core\Payum;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class PaymentController extends AbstractController
{
    private Payum $payum;

    public function __construct(Payum $payum)
    {
        $this->payum = $payum;
    }

    #[Route('/payment', name: 'payment')]
    public function index(): Response
    {
        $storage = $this->payum->getStorage(Payment::class);

        /** @var Payment $payment */
        $payment = $storage->create();
        $payment->setNumber(uniqid());
        $payment->setCurrencyCode('EUR');
        $payment->setTotalAmount(123); // 1.23 EUR
        $payment->setDescription('A description');
        $payment->setClientId('anId');
        $payment->setClientEmail('foo@example.com');

        $storage->update($payment);

        $captureToken = $this->payum->getTokenFactory()->createCaptureToken(
            'paypal_express_checkout',
            $payment,
            'done' // the route to redirect after capture
        );

        return $this->redirect($captureToken->getTargetUrl());
    }
}

Seems to be a problem with the https://github.com/thephpleague/uri package that is used in payum/payumb/c the packages changed and moved the methodes in it's own packages. Currently the bundle is not useable :(

@tsdevelopment What version of payum/core do you have?

Can you please try changing your composer.json to use

{
    "require": {
        "payum/core": "dev-master"
    }
}

and run composer update payum/core?

In the master branch, there has been some changed to thephpleague/uri to support the latest version, so maybe that can fix your issue.

Hello, I have the same problem on Symfony 5.2.

Attempted to load class "MergeQuery" from namespace "League\Uri\Modifiers".
Did you forget a "use" statement for another namespace?

========
#vendor\payum\paypal-express-checkout-nvp\Payum\Paypal\ExpressCheckout\Nvp\Action\PurchaseAction.php (line 70)

  if ($details['CANCELURL']) {
      $cancelUri = HttpUri::createFromString($details['CANCELURL']);
      $modifier = new MergeQuery('cancelled=1');
      $cancelUri = $modifier->process($cancelUri);
      $details['CANCELURL'] = (string) $cancelUri;
  }

My composer.json :
"require": {
