Error
Notice: Undefined offset: 0 in vendor/magento/module-configurable-product/Model/Product/Type/VariationMatrix.php on line 43
Process
We were importing a csv with column "configurable_variations" and values = "sku=costdai-ama-dail-p10-moon-stone-sp0000,sphere=0.00,contact_lens_color_name=Moon Stone| sku=costdai-ama-dail-p10-moon-stone-sn0050,sphere=-0.50,contact_lens_color_name=Moon Stone"
Solution and Reason
The reason of above error is the child product (costdai-ama-dail-p10-moon-stone-sp0000) does not have values assigned for attribute "contact_lens_color_name=Moon Stone"
So if we set the values to child product and try reimporting again. The parent product will be created with 2 child products assigned. We can see the child products on admin when we edit the parent product, under Configurations -> Current Variations
