Problem with executing dynamic custom actions on rasa X serwer

I am able to successfully implement custom action on my local computer my follow this video:

and rasa give me following respond:

Your input → Hi what time is it
Current date and time = 2021-05-25 19:06:42.133997

Is perfectly fine! However when I am doing push to my git and then rasa X is pulling those changes correctly I am not albo te get response inside rasaX I see that intent ‘give_time’ is recognised correctly in this case, but after that nothing happend… I also know that custom actions on rasa x works, because when I swith this action to some static respond I am able to get the answer on rasaX serwer. The problem is with dynamic responses. What can I do in this case?

I find out the answer, dispatcher has to take a string as a argument:

class ActionShowTime(Action):

def name(self) -> Text:
    return "action_show_time"

def run(self, dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:

    t =
    respond_str = str("Current date and time = %s" % t)

    return []
