How to pass a Java byte[] to the ScriptEngine Nashorn as parameter?

[Hao Guo]

This is my code to call a JavaScript function in Java:

*// create a script engine manager
ScriptEngineManager factory = new ScriptEngineManager();
// create a JavaScript engine
System.setProperty("nashorn.args", "--language=es6");
ScriptEngine engine = factory.getEngineByName("Nashorn");
engine.eval("function transformPayload(rawData) { return rawData }");
Invocable invokeEngine = (Invocable) engine;
var rawData = "{\"keyOne\": \"Value one\",\"keyTwo\": \"Value
two\"}".getBytes();
return invokeEngine.invokeFunction("transformPayload", rawData);*

After I execute the script, I have a String but not a byte[], I also
can't execute the logic of processing JavaScript byte[] in this code.
