OpenWhisk Python action failing with not returning dictionary error

Question

I am trying to run this function with OpenWhisk:

def main():
    return {"payload": "Hello world"}

With the following:

> bx wsk action create hello_python hello_python.py
> bx wsk action invoke hello_python

When running the function locally a dictionary is returned, but running the above gives this error:

"result": {
        "error": "The action did not return a dictionary."
    }

What am I missing here?

Change your code to:

def main(args):
    return {"payload": "Hello world"}

That looks exactly the same to what I had, is the args missing from `def main(args)`. Thanks for the link to the docs! – Margriet Jun 13 '18 at 17:49
Sorry, when I copied your code, I forgot to add the "args". Now the answer is correct. – data_henrik Jun 13 '18 at 18:11

main() input can't be empty takes a dict like main(args)

def main(args):
    return {"payload": "Hello world"}
