Error while trying to create a local task for user order history

I am attempting to add a local task here (/admin/commerce/orders/{order#}). This local task should contain a view that takes the userid from the current order and displays that users order history.

I believe I have the view set up correctly and I can successfully add a local task here (admin/people/%user/orders) by adding the following to my links.tasks.yml:

  custom_module.people.user_orders:
    route_name: view.orders.page_2
    base_route: entity.user.canonical
    title: 'Orders'
    parent: entity.user.canonical
    weight: 100

If I go to /admin/people/1/orders while this task is uncommented, I do indeed get a list of this user's orders and the tab itself lives under the Home>Administration>People part of the site.

However, if I remove this local task and replace it with the following, I get an error:

  custom_module.commerce_order.user_orders:
    route_name: view.orders.page_2
    base_route: entity.commerce_order.canonical
    title: 'Orders'
    parent: entity.commerce_order.canonical
    weight: 16
    class: '\Drupal\custom_module\Plugin\Menu\UserOrdersDynamicTab'

UserOrdersDynamicTab.php:

namespace Drupal\custom_module\Plugin\Menu;

use Drupal\Core\Menu\LocalTaskDefault;
use Drupal\Core\Routing\RouteMatchInterface;

class UserOrdersDynamicTab extends LocalTaskDefault
{

  /**
   * {@inheritdoc}
   */
  public function getRouteParameters(RouteMatchInterface $route_match)
  {
    return [
      'user' => \Drupal::routeMatch()->getParameter('commerce_order')->getCustomerId(),
    ];
  }
}

Uncommenting this version and commenting out the previous local task results in an error when I visit /admin/people/1/orders. To be clear, I am trying to create a local task that passes a parameter to a view. Below is the error I am getting. Thank you in advance for any help you can offer! (This is my first time posting a question here so I'm also interested in corrections to my post.)
