M2 show simple product sku in shopping card of configurable product

[senders]

Hi @Damian Culotta,

and the sku is displayed by the normal magento function here:

vendor\magento\module-checkout\view\frontend\templates\cart\item\default.phtml

I would be also helpful, to know how to get the simple product sku from the configuration product without the is_visible_checkout option, so I can insert it manually in a copy of default.phtml

Right!

Without checking the code I could assume that, if you are using a complex type of product, to get the child SKU you need to apply some validation.

In this case, probably, the extension is just getting the attribute for a given product without checking if the product has childs or parent.

My guess is that the issue you reported could be related with that.
