M2.4.3, v1.1.6: Cannot change the SKU with stocks assigned to the given product

ISSUE:

If I want to change my SKU with stocks assigned to the given product (MSI enabled and multiple sources in use), I cannot change the SKU and I get the attached stack trace. Workaround: Unassign Product from all stocks, change SKU and assign stocks back to the product. 

SOLUTION:

There is a bug in our Inventory Report module. The getSalableQty is calling the validateProductType function. This function needs to pass in productType, but when changing the SKU, the product type cannot be saved into the catalog_product_entity table => the input parameter is null

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

Or download the file attached below to override the current file on your site.
