> When the last expression in a script returns a JSON object, this is returned as String {{[object Object]}}. E.g.
> {code}
> var obj = { k: 1, v: 2}
> obj
> {code}
> This is because ScriptingEngine's eval method returns an instance of javax.script.Bindings (as ScriptObjectMirror) which is a Map<String, Object>.
> Our integration layer should detect the type of the returned object and adjust it for the consumer. 
> A simple workaround is to wrap the final object around {{JSON.stringify}} call, e.g.
> {code}
> var obj = { k: 1, v: 2}
> JSON.stringify(obj)
> {code}
