Hi all! I’m trying to do a chatbot on facebok messenger.So I want to send the user a welcome message containing his surname and name. However, while running the code, I get this error: Encountered an exception while running action ‘action_welcome_with_name’. Bot will continue, but the actions events are lost. Make sure to fix the exception in your custom code.

I try to add an endpoint: http://localhost:5055/webhooks. But this didn’t solve the problem and I get now this error along side with the last one: Failed to run custom action ‘action_welcome_with_name’. Couldn’t connect to the server at ‘http://localhost:5055/webhooks’. Is the server running? Error: Cannot connect to host localhost:5055 ssl:None [Connection refused]

My guest is that it is the endpoint which is not properly set. But I’m wondering which endpoint from facebook I need to specify there in other for the action to take place ?

Can Anyone help please ? Quiet new to rasa.

Hi @Rogers_ntr, i would suggest testing your bot locally before trying to deploy it on facebook. It looks like in this case

Couldn’t connect to the server at ‘http://localhost:5055/webhooks’. Is the server running?

You’re not running your action server. You can run the action server with rasa run actions.

Did you connect your bot as described here Messaging and Voice Channels ? If so, then you can also send messages to the user by doing dispatcher.utter_message("Hello World!") instead of doing the web request.

Thanks all for your reply. I already solved the problem. It was not configuring the proper webhook plus The action server was not running.

Thanks anyway.

The above exception was the direct cause of the following exception:

Insted of returning firstname and lastname to slots is okay to use it in this way>

r = requests.get(
                'https://graph.facebook.com/{}?fields=first_name,last_name,profile_pic&access_token={}'.format(
                    sender_id, access_token)).json()
            first_name = r['first_name']
            last_name = r['last_name']

dispatcher.utter_message("Hey " + first_name + " " + last_name +"!  I’m Rick")
