Hi, guys
Currently, openwhisk supports return json object only,
I wrote a POEM in openwhisk upstream that allows user to write their own action
which supports array result. e.g. already implmeneted in my local env for
python, worked well
```
def main(args):
try:
name = args.get("name", "World")
place = args.get("place", "Naver")
return ["a", "b"]
except Exception as e:
# please handle exception here
# you can return or hide an error message
return {"error": str(e)}
```
So the result will support object and array both in future.
