Success instead of expected failure in Action result

Python runner code

def run(self):
        r = requests.get('https://google.com')
        print r
        return (False, r)

I expect the status to be 'failed' because I am returning False as the tuple's status indicator, per the documentation. Actual output:

.
id: 585486e602ebd502e0980392
status: succeeded
parameters:
result:
  exit_code: 0
  result: None
  stderr: ''
  stdout: '<Response [200]>

    '

The same thing happens when I use self instead of r - the issue might happen when any object is returned as part of the tuple. The docs imply that the result can be any value:

If the run method finishes without exceptions, the execution is successful, and the value returned by the method (any value: boolean, string, list, dict, etc.) is considered its result. Raising an exception will report the execution as failed.
