    {
        $customerId = $this->settingsService->getSetting('settings-customer-id');
        $dataUserIdToken = $this->paypalService->getVaultService()->getDataUserIdToken($customerId);

It seems like $customerId can also be of type null; however, parameter $clientId of App\Service\Paypal\VaultService::getDataUserIdToken() does only seem to accept string, maybe add an additional type check?

        return $this->render('paypal/vault/'. $action .'.html.twig', [
            'dataUserIdToken' => $dataUserIdToken,

        ]);
    }
