How to solve “Can’t determine what item to use”?

From all the documentation listed below, two things I couldn’t understand were:

This is my workflow. I have implemented “Item linking in the code node” in “Merge All Fields Code” node.
In “Handle Both Node Data Code” node handles both “Merge All Fields Code” and returning items. Code is about if there are returning items then only those fields will be updated to “Merge All Fields Code” values. In LLM Chain. it returns only 1 field. I can’t add more fields. But now in “Ai Resume Fields” Node i need some fields to map here. I can’t map.

Any solution how to implement this type of flow?
