Data Action output returns undefined despite valid JSON response

"result": undefined

My OTel span shows the downstream API returned 200 with valid JSON. The Data Action config maps the response body correctly, but the output variable in Architect is undefined.

  • Provider: REST
  • Method: GET
  • Response Schema: Defined with type: object
  • Mapping: $.data.value
  • Debug Logs: Show raw JSON in response.body

The mapping path looks right. What’s breaking the extraction?
