recipe definition and payload

These functions are missing the return statement.

def set_payload(self, payload):
    """
    Set the raw payload of this recipe
    :param str payload: the payload, as a string
    """
    self.data['payload'] = payload

def set_json_payload(self, payload):
    """
    Set the raw payload of this recipe
    :param dict payload: the payload, as a dict. The payload will be converted to a JSON string internally
    """
    self.data['payload'] = json.dumps(payload)

Start by locating the recipe definitions of set_payload and set_json_payload, then inspect how callers use these methods and whether similar methods return a value. Confirm the intended return behavior from the surrounding API client conventions and add coverage or verification for both payload setters before considering the issue done.
