If the action server is not running and Rasa is trying to run a custom action, it will receive an error that is catched here: [rasa/action.py at master · RasaHQ/rasa · GitHub](https://github.com/RasaHQ/rasa/blob/master/rasa/core/actions/action.py#L431). Finally, the raised exception will be catched here: [rasa/processor.py at master · RasaHQ/rasa · GitHub](https://github.com/RasaHQ/rasa/blob/master/rasa/core/processor.py#L466). No action is executed and no event is added to the tracker. We just log the error. So, unfortunately you cannot catch the error and handle it differently. ---

I am getting multiple responses from Facebook messenger when my server starts from off. Can I handle the requests in Rasa. I think it sending multiple requests when server is starting that’s why gives multiple responses. ---

What request are you talking about? As far as I know we only handle incoming user messages from Facebook. We ignore other messages.The incoming messages are processed and a respond is send via the Facebook channel. However, if you want to handle more messages, you can adapt the existing Facebook Connector to handle more messages ([Custom Connectors](https://rasa.com/docs/rasa/user-guide/connectors/custom-connectors/)). ---

I am talking about response that we give back to Facebook. So tell me I can control it or not. I think it is more related to how internet works like GET and POST. Just tell is there is any way to control responses. If any… ---

@Tanja @erohmensing, I want to handle the exceptions for API calls in rasa action server. For example, In the rasa action server, I host a local server for API call. If the server is Not Found, I have to respond the user that the requested server is not found and I want to respond the user to make a valid request. Could you give some information on this? I have tried to implement this using requests.status\_code and throw a message in the action server. But, I want to send the message as a response while interacting to the user in the rasa server ``` if r.status_code == 200: process_message = "The client request has succeeded" logger.info(process_message) ``` for which, The output is > 127.0.0.1 - - [2019-10-29 12:39:25] “POST /webhook HTTP/1.1” 200 169 0.030977 > 127.0.0.1 - - [2019-10-29 12:39:37] “POST /webhook HTTP/1.1” 200 226 0.001980 > 2019-10-29 12:39:38 INFO root - The client request has succeeded > {‘Addr’: None, ‘Area’: ‘centre’, ‘Day’: None, ‘Food’: ‘italian’, ‘Name’: None, ‘People’: None, ‘Phone’: None, ‘Post’: None, ‘Price’: None, ‘none’: None} > 2019-10-29 12:39:38 ERROR rasa\_sdk.executor - Your action’s ‘Action-Search’ run method returned an invalid event.
