Issue
availability'/'condition'/'mpn' is not connected to a field, check the mapping in 'Mapping'
What does this issue mean?
This issue means that you have not linked an 'Internal field' to the 'Channel field name' in the Mapping step.
How do I solve this issue?
To solve this issue, you need to link an 'Internal field' to the channel field name in the Mapping step. For example, for the 'Channel field name' 'availability' you can link the 'Internal field' 'availability'.
