I am using Magento2.2.6 and in admin side go to manage product and edit configurable product getting this error below

Notice: Undefined offset: 0 in /XXX/data/home/256705.XXXXX.com/XXXXX/public_html/vendor/magento/module-configurable-product/Model/Product/Type/VariationMatrix.php on line 43

If any one facing this issue and have you get any solutions reply me.

Thanks In advance.


The problem is, we had a configurable product set to use with two configurable attributes.

However, one or more of the simple products that were associated did not have a value for the configurable attribute.

Presumably, the products did have this value at one point but the values were removed after the product had been linked up.

The solution was to populate the simple product attribute values. This means you can then edit the configurable product and remove that configurable attribute from the product if required.

i hope its very helpful to you
