I am trying to update magento 2 products and save by programmatically and getting error “value index is not specified for an option magento 2”.
Please have me to solve this issue!!
Thanks in advance.
Few days ago i am also getting same issue but i have resolved this issue.
If you have migrated database from magento 1.x to magento 2.x and you are getting this issues with configurable products, one product showing other product attributes then you need to go in product back-end and set all configurable attribute with manual process and save that product, your issues will resolve.
You can do this by code but if your product assign with dot or blank configurable value then you need to do those product by manual process.
