From Vasilis Vagias:

evaluateJsonPath immediately after the InvokeHTTP and replace the flowfile content with the $.response then NiFi unescapes and removes the additional quotes auto magically.

This is helpful for occasions when CDSW returns JSON or other REST APIs which may double encode JSON files.
