I am running the following command

python -m rasa_core.run -c rest  -d data/servicing-bot-en/models/dialogue -u data/servicing-bot-en/models/servicing-bot-en/model-en --endpoints endpoints.yml --credentials credentials.yml

with the following message

POST /webhooks/rest/webhook HTTP/1.1
Host: localhost:5005
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 99e5cd1e-fc3e-e0eb-3827-6be81982a603

{
	"sender":"Souvik",
	"text":"i have lost my card"
	
}

Any idea what is wrong here

I found the isssue, turns out there is an error in the documentation - https://rasa.com/docs/core/connectors/#restinput

The post message should be

POST /webhooks/rest/webhook HTTP/1.1
Host: localhost:5005
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 99e5cd1e-fc3e-e0eb-3827-6be81982a603

{
	"sender":"Souvik",
	"message":"i have lost my card"
	
}

@akelad, @tmbo - Can you please check if this is the case because in the documentation for rest channel vs http api - the POST data request structure isn’t the same.
