Validating slots in rasa 2.0

@erohmensing Sorry, for this i uploaded a sample code, actually my original code looks like this

class ValidateBuyHomeForm(FormValidationAction):

def name(self) -> Text:

    return "validate_buy_form"

@staticmethod

def name_of_slot() -> List[Text]:

    """Database of supported cuisines"""

    return ["name","pre_city", "cost", "property_type","bedrooms","bathrooms",

    "months","phone_number","email"]

    

def validate_slot(

    self,

    value: Any,

    diapatcher: CollectingDispatcher,

    tracker: Tracker,

    domain: Dict[Text, Any],

    ) -> Dict[Text, Any]:

    if value.lower() in self.name_of_slot:

        return {"name": value,"pre_city": value,"cost": value,"property_type": value,

        "bedrooms": value,"bathrooms": value,"months": value,

        "phone_number": value,"email": value}



def submit(

    self,

    dispatcher: CollectingDispatcher,

    tracker: Tracker,

    domain: Dict[Text, Any],

    ) -> List[Dict]:

    dispatcher.utter_message("utter_submit_buy", tracker)    

    return []

class ValidateSellHomeForm(FormValidationAction):

def name(self):

    return "validate_sell_form"



@staticmethod

def name_of_slot() -> List[Text]:

    """Database of supported cuisines"""

    return ["name","address", "city", "zipcode","size","layout","time_to_sell","phone_number","email"]

    

def validate_slot(

    self,

    value: Any,

    diapatcher: CollectingDispatcher,

    tracker: Tracker,

    domain: Dict[Text, Any],

    ) -> Dict[Text, Any]:

    if value in self.name_of_slot:

        return {"name": value,"address": value,"city": value,"zipcode": value,

        "size": value,"layout": value,"time_to_sell": value,"phone_number": value,"email": value}



def submit(

    self,

    dispatcher: CollectingDispatcher,

    tracker: Tracker,

    domain: Dict[Text, Any],

    ) -> List[Dict]:

    dispatcher.utter_message("utter_submit_buy", tracker)    

    return []

My form name is also buy_form. My forms looks like this:

forms:

buy_form:

name:

  - type: from_text

    action: utter_ask_name

    auto_fill: false

pre_city: 

  - type: from_text

    action: utter_ask_pre_city

    auto_fill: false

cost: 

  - type: from_text

    action: utter_ask_cost

    auto_fill: false

property_type:

   - type: from_text

     action: utter_ask_property_type

     auto_fill: false 

bedrooms:

  - type: from_text

    action: utter_ask_bedrooms

    auto_fill: false   

bathrooms:

  - type: from_text

    action: utter_ask_bathrooms

    auto_fill: false 

months:

  - type: from_text

    action: utter_ask_months

    auto_fill: false 

phone_number:

  - type: from_text

    action: utter_ask_phone_number

    auto_fill: false 

email:

  - type: from_text

    action: utter_ask_email

    auto_fill: false

So. this is not the problem in naming system it should be something else. This is the warning i get in every slot :
