Notice: Undefined offset: 0 in vendor/magento/module-inventory-configurable-product-admin-ui/Observer/ProcessSourceItemsObserver.php on line 83

[ioweb-gr]

Preconditions (*)

1. 2.4.1
2. One configurable product and children with sources assigned
3. Multiple websites and store views
   E.g.

Steps to reproduce (*)

1. Try to save the configurable product in a different store view than the Default

Expected result (*)

1. Product is saved correctly

Actual result (*)

1. The product is saved but a notice appears

I've tried debugging this a bit and it seems that in line
vendor/magento/module-inventory-configurable-product-admin-ui/Observer/ProcessSourceItemsObserver.php:75

The productsData array is indexed by 0...N

But later on the function $product->getExtensionAttributes()->getConfigurableProductLinks()

Will return an array indexed by the productId and not with a number 0...N

However when repeating this on the default store view the case is different and everything works fine.

Any ideas why it's loading the product links differently per store?
