[Bircoff]

Hello, I'm trying to migrate with assistance Magento Migration Tool from Magento 1.9.3.6 to Magento 2.2.1 I can't overcome this error messages:
"[ERROR]: Incompatibility in data. Source document: eav_attribute_group. Field: attribute_group_name. Error: The product attribute set "Handheld Scopes" does not contain all required attribute group names "General, Prices, Design, Images".
Did you know where I must look for a problem?

Could you check Handheld Scopes attributes in Magento 1. I think might be issue related to attribute set with not defined groups. If those attributes are not used in your M1 site then kindly remove it from Magento 1 and try again to migration.

Might be issue solved using remove those unnecessary attributes from magento1.
