I have an post on my blog about how to read in a flow file containing JSON using ExecuteScript with ECMAScript:

There is also another StackOverflow question similar to your use case of reading in a mapping file and applying it to incoming data (using Groovy):

Apache NiFi ExecuteScript: Groovy script to replace Json values via a mapping file

Not sure if this helps too but I have another post on validating JSON with ExecuteScript (but Groovy not ECMAScript) using JSONSchema: http://funnifi.blogspot.com/2016/05/validating-json-in-nifi-with.html
