How to fix async.io error

Hi, I have installed rasa_core, then i did pip install rasa x. I have the latest versions of both rasa core and rasa x. I have connected my bot to the database and I am fetching the data from there.Here is the code. I do rasa run actions and then rasa shell

class ActionHelloWorld(Action):

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

def run(self, dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
    # Getting slot values
  insert_date=tracker.get_slot('insert_date')
  receiver_email=tracker.get_slot('email')
  entity_name=tracker.get_slot('entity_name')  
  print("entity_name",entity_name)
  print("email",receiver_email)
  print("insert_date",insert_date)
  
  user = "postgres"
  password = "postgres"
  host = "localhost"
  port = 5432
  database = "mydatabase"

  db_conn = psycopg2.connect(host=host, user=user, password=password, database=database)
  db_cursor = db_conn.cursor()
  sql_query = "SELECT * FROM operational_metadata WHERE entity_name = %s and insert_date = %s ;"
  print("i am good")
  result = db_cursor.execute(sql_query,(entity_name,insert_date,))
  results1 = db_cursor.fetchall()
  for r in results1:
      response={"entity_name :{r[0]}  insert date :{r[1]}   label :{r[2]}"}
      print("------------------------",response)
  dispatcher.utter_message(response)
  

  return [SlotSet('email', receiver_email), SlotSet('entity_name', entity_name), SlotSet('insert_date', insert_date)]

I got this in the terminal running rasa shell:

I get no error in the terminal that runs rasa run actions

Hi @gandharv30!

I think the error is because the response is not a string.
