This issue seems to happen when the default stock is not the original Magento stock but a newly created stock set as default for the Main website.

Additional Information

Upon further investigation, it appears the issue may be related to the logic in \Magento\InventoryConfiguration\Model\GetStockItemConfiguration::execute, specifically line 71, where there's a check $this->defaultStockProvider->getId() !== $stockId. Altering the return value in \Magento\InventoryCatalog\Model\DefaultStockProvider::getId from 1 to 2 (the ID of the new default stock) seems to resolve the issue. However, it's unclear if this change might affect other areas of the system. This behavior suggests a potential oversight in handling custom default stocks when 'Manage Stock' is set to 'No'.

Hello.

What happens if no stock source is assigned? The same error appears in that case as well. If a product is discontinued and won't be sold again, shouldn't merchants be able to unassign stock to prevent unnecessary calculations in the stock index? Currently, doing so also triggers this error also.

Thank you.
