Anonymous payment error after return from paypal

@Utilvideo , I have fixed the issue and created Patch.

Thanks.

+1 Confirm worked.

Hello Everyone,
I have encountered this same bug and saw in the codebase https://git.drupalcode.org/project/paypal_subscriptions/-/blob/2.0.x/src...

  /**
   * {@inheritdoc}
   */
  public static function create(ContainerInterface $container, array $configuration, $plugin_id, $plugin_definition) {
    $instance = parent::create($container, $configuration, $plugin_id, $plugin_definition);
    $instance->current_user = $container->get('current_user');
    return $instance;
  }

The
$instance->current_user = $container->get('current_user'); should be $instance->currentUser = $container->get('current_user');
The protected property is:
protected $currentUser;

abhishek_gupta1 Did a great job with the patch and I have built up more on this to fix the property declaration and some error handling.

I have run tests with a Drupal Commerce install using Commerce Recurring.

I added the PR and can test this patch. Please let me know if there needs to be changes or the error handling logic needs to be stripped out.

"I do not agree with the patch. Why can't an anonymous user subscribe on PayPal?
Suggestion: Load the user if they exist. If not, allow an anonymous donation.
I don't think the 'name' value from the user is strictly required. We should make it dependent on whether the user is logged in. If they are logged in, get the name; if not, use 'Anonymous' as the default."
'SUBSCRIBERNAME' => $account->get('name')->value,

In my donation charity for girl, it used for anonymous users....
