Data Action fails on Cognigy token payload with 400

Hitting the Cognigy profile endpoint via a GET Data Action and getting a 400 Bad Request on the parse step. The response is valid JSON but the schema validator in Architect complains about the nested token object structure. Here’s the mapping JSON:

{
 "attributes": {
 "profile": "{{ $.response.body.profile }}"
 }
}

The error says it can’t resolve the path. What am I missing?
