During Magento1.9.3.4 to Magento2.1.8 Migration Getting following issues :-
Incompatibility in data. Source document: eav_attribute_group. Field: attribute_group_name. Error: The product attribute set "Default" does not contain all required attribute group names "General, Prices, Design, Images"
I've attached screenshot.
Note:- Also implement R&D solutions but issue still not resolved.
