Utter_button_message exceptions using rocketchat channel

Rasa Open Source
1

I am using a custom action to generate a dynamic array of buttons and while this works as expected using other output channels, I receive the following exception when this exchange is made using a rocketchat endpoint:

[2019-07-10 10:18:58 +0000] [1] [ERROR] Exception occurred while handling uri: 'http://rasa:5005/webhooks/rocketchat/webhook'

    for b in buttons
KeyError: 'payload'

and the relevant code snippet:

        srv = client.service_check()
        buttons = []
        for host in srv:
            buttons.append({"title": host["name"], "payload": host["name"]})
        dispatcher.utter_button_message(
            "On which hosts should I {} the {} service?".format(state, service), buttons
        )

        return []

I can’t find any outstanding issues related to this. Any help would be appreciated.

Thanks in advance

Hm this is strange, I cant see any immediate reason why your code wouldn’t work. What versions of rasa and rasa-sdk are you on?

Can you put in a debugging statement and tell me the value of buttons at this point: rasa/rocketchat.py at master · RasaHQ/rasa · GitHub

I’m using the latest docker image for both.

Buttons would look something like this: [{"title": "server1", "payload": "server1"}, {"title": "server2", "payload": "server2"}]

Thinking the error could have been caused by the lookup used in generating the buttons array I tested with static values and got the same result; however, using a button template renders as expected.

I’ve tested this on rocketchat version 1.2.1 and 1.0.3

Regretfully, the action file contained some code left over from testing and was not reflecting my local changes.

The bad code caused the buttons array to contain an item without a payload.

Thanks for your time @erohmensing and for being my rubber duck. :duck:
