I have to handle API call exceptions in Rasa action server. For Example, I have a list of restaurant databases, which I will host it in a local server. In rasa action server, I would host this local server and access information from the database. If wrong database has hosted, it throws 501 http error. When this error occurs, I can now log this error,but I would like to send a message as a response to user. > If 501 error occurs, ``` For, User Input: Can you look for cheap restaurant in centre of town system output: I am sorry for the inconvenience, I have encountered an Internal service error. Could you please try again later ``` How can I handle this in Rasa action server? Could I get any information regarding this? ---

How are you making API calls from `actions.py` ? If you are using requests package, then it should be quite easy. ---

Inside the run method of your Action class, you can use requests to make API call like this: ``` try: log.debug(f'URL for API: {_url}') resp = requests.get(_url) except requests.exceptions.RequestException as e: s = getattr(e,'message', str(e)) log.error(f'Unable to get data due to {s}.') message = 'I am sorry for the inconvenience, I have encountered an Internal service error. Could you please try again later' dispatcher.utter_button_message(message) ``` ---

Hi @tonysinghmssThanks for the reply. I have tried it, but still it throws me an exception instead of an error message In run() method of my action class, I have defined as follows, > class RestaurantInform(Action): def name(self): return “Restaurant-Inform” > > ``` > def run(self, dispatcher, tracker, domain): > try: > count, specific_data, name, addr, ph_no, post_code= ActionSearchRestaurants.entity_extract(self, dispatcher, tracker, domain) > > if len(specific_data) != 0: > message = dispatcher.utter_message(f"There are {count} options available. The list of Restaurant names are {specific_data}. Could you tell me which one do you prefer?") > return message > elif len(addr)!=0 and len(ph_no)!=0 and len(post_code)!=0: > message_1 = dispatcher.utter_message(f"The restaurant {name} is located at {addr} and their phone number is {ph_no}. The post code of the restaurant is {post_code}") > return message_1 > else: > pass > except requests.exceptions.RequestException as e: > s = getattr(e,'message', str(e)) > logger.info(f'Unable to get data due to {s}.') > message = 'I am sorry for the inconvenience, I have encountered an Internal service error. Could you please try again later' > dispatcher.utter_message(message) > > ``` Instead of giving me the message ``` message = 'I am sorry for the inconvenience, I have encountered an Internal service error. Could you please try again later' ``` I get the following exception, > Your input → can you look for cheap restaurants in centre of town? > Could you give me some other suggestion? > 2019-11-06 11:09:56 ERROR rasa.core.processor - Encountered an exception while running action ‘Action-Search’.

Can you put log of your` actions.py`? That will help in better understanding of your issue. ---

Hi, Could you please suggest, how to track information, errors in a logger? I a using the below codes in my action file but it’s not capturing anything, neither any log files created as of now. (its also not showing any error. ``` import logging logging.basicConfig(filename='logfile.log', format='%(asctime)s - %(levelname)s - %(name)s - %(message)s', datefmt='%m/%d/%Y %I:%M:%S %p') logger = logging.getLogger( __name__ ) def submit( self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any], ) -> List[Dict]: try: ........ ........ ........ except Exception as e: msg = 'Unfortunately I am not able to extract requested information!
You can still contact us via email 🙂' dispatcher.utter_message(text= msg) logger.error(e) # logger.exception() logger.exception("Failed to extract data for " + project + "(" + query + ")") return [] ``` Will appreciate your response.
