M2.4.3, v1.1.6: Error when creating a product with same SKU as a deleted product

Created by Esther Nguyen, Modified on Mon, 01 Nov 2021 at 02:18 PM by Esther Nguyen


We've got a problem with trying to recreate a product with the same SKU as a previously deleted product. Basically, I deleted a couple of products that were in order, and that means that the order now cannot be shipped or credit memo on the system. In the past (on 2.3.5) I have been able to simply create a new product with the same SKU as the old one, and then we're usually able to ship the order. However, we've just tried to do this (create a new product with the same SKU as the old one) and it gives us this error:

TypeError: Argument 1 passed to Magento\InventoryConfiguration\Model\IsSourceItemManagementAllowedForProductType\Interceptor::execute() must be of the type string, null given, called in /home/474972.cloudwaysapps.com/aatutsngpq/public_html/vendor/magento/module-inventory-sales/Model/GetProductSalableQty.php on line 108 and defined in /home/474972.cloudwaysapps.com/aatutsngpq/public_html/generated/code/Magento/InventoryConfiguration/Model/IsSourceItemManagementAllowedForProductType/Interceptor.php:20


When catching the "before save product" event, the get Salableqty function has not covered the case where the product has no source yet. As a result, when the product is deleted, there is no productType existing, and the function that checks allow product type will report an error. 

To resolve the issue, please edit the file: app/code/Bss/InventoryReport/Observer/SaveObserver.php as below:
