Hello Community,
I’m trying to create an easy way to change the content of my bots utterances. So I added an endpoint like described here
action_endpoint:
url: "http://localhost:5055/webhook"
nlg:
url: http://localhost:80/utter.php # url of the nlg endpoint
My utter.php atm only returns the response for the first utterance for testing purposes, so it always returns following JSON (with MIME application/json):
{
"text": "In welcher Phase des Projektes befindet ihr euch?",
"buttons": [{"title": "Anfang", "payload": "/set_phase{\"Phase\": \"Anfang\"}"},
{"title": "Planung", "payload": "/set_phase{\"Phase\": \"Planung\"}"},
{"title": "Umsetzung", "payload": "/set_phase{\"Phase\": \"Umsetzung\"}"}],
"image": null,
"elements": [],
"attachments": []
}
which triggers following errormsg on the rasa core server:
2019-03-21 12:25:19 ERROR rasa_core.processor - Encountered an exception while running action 'utter_phase'. Bot will continue, but the actions events are lost. Make sure to fix the exception in your custom code.

Any idea what went wrong? Jsonlint tells me, that this is valid JSON, looking into your documentation, the content seems to be fine to - but still, I get this error and the message is not getting pushed to the socket.io api
