Issue

Prerequisites:

Install Magento with Inventory Management.

Steps to reproduce:

1. Go to Admin.
2. Create a simple product.
3. Create a virtual product.
4. Create a bundle product (Create two dropdown options for child products, and assign virtual and simple products.). Set Dynamic Price = No.
5. Go to the storefront.
6. Go to the product's page.
7. Add the product to cart.
8. Proceed to checkout, and order the product.
9. Go to Admin > Orders.
10. Open the created order, and invoice it.

Expected results:

Actual results:

The invoice is not created, and you receive an error similar to this:

TypeError: Return value of Magento\InventorySourceSelection\Model\Request\InventoryRequest::getItems() must be of the type array, null returned in vendor/magento/module-inventory-source-selection/Model/Request/InventoryRequest.php:102
