For an attribute to be imported, each option-value needs to be created via either separate DbIo import or the admin's Catalog / Options Names Manager. The message you're receiving indicates that the option value doesn't exist or that the option-name its 'associated with' doesn't have an options_id of 7 (which is what's specified in the DbIo input record).
So I believe I understand the issue, I am not sure how to resolve it.
I took a smaller sample of the basic attributes values and attempted to import, but received a similar response as follows:
✗ Attributes not inserted at line number 2; no match for option name::option_type::default_language_id (Bedroom::0::1).
✗ Attributes not inserted at line number 3; no match for option name::option_type::default_language_id (Bedroom::0::1).
✗ Attributes not inserted at line number 4; no match for option name::option_type::default_language_id (Bedroom::0::1).
The import of product options and product options values processed without an issue, however the basic attributes is still giving me trouble. I am also including a screenshot of the option values with names for reference. Any suggestion to resolve? Thanks again.
