Asyncio - Task exception was never retrieved

I keep getting exception error in the last step of executing an action Task exception was never retrieved future: <Task finished coro=<configure_app..run_cmdline_io() done, defined at c:\users\crizma-technology\anaconda3\envs\rasa_envs\lib\site-packages\rasa\core\run.py:128> exception=TimeoutError()>
I am taking Sara assistant as an example so most probably my code is ok rasa version is 1.10.1 and rasa-sdk==1.10.1 here’s the action code

class SalesForm(FormAction):

    """Collects sales information and adds it to the spreadsheet"""

    def name(self):

        return "sales_form"

    @staticmethod

    def required_slots(tracker):

         return [

        "job_function",

        "use_case",

        "budget",

        "person_name",

        "company",

        "business_email",

        ] 

    def submit(

            self,

            dispatcher: CollectingDispatcher,

            tracker: Tracker,

            domain: Dict[Text, Any],

        ) -> List[Dict]:

        #dispatcher.utter_message("Thanks for getting in touch, we’ll contact you soon")

        budget = tracker.get_slot("budget")

        company = tracker.get_slot("company")

        email = tracker.get_slot("business_email")

        job_function = tracker.get_slot("job_function")

        person_name = tracker.get_slot("person_name")

        use_case = tracker.get_slot("use_case")

        sales_info = [budget, company, email, job_function, person_name, use_case]

        dispatcher.utter_message(sales_info)

        return []

Solved: it was an error in dispatcher.utter_message() it takes only string
