Add the Map JSON fields action after a workflow step that returns JSON text.
1. Pass the JSON response text into json_text.
2. Add one path-map rule per line, for example:
name=contact.name|required|type=text
email=contact.email|required|type=text
price=items[0].price|type=number
3. Use mapped_values_json, error_code, and error_message in the next workflow step.

Supported types: text, number, yes/no, list, object, null. Basic repair mode removes common wrappers around valid JSON only; it does not invent missing values.
