How to fix: Missing attribute value for grouped variants

Submit this value for all product variants in the same group

You’ve submitted multiple products that use the same item group ID [item_group_id], but don’t consistently include the same variant attributes. Variant attributes help to differentiate products that are similar, but vary by distinct features, such as size [size], color [color], condition [condition], or gender [gender]. To ensure that we can correctly identify your products, either provide the same set of variant attributes for all products that use the same item group ID [item_group_id], or do not provide the item group ID [item_group_id] for these products.
