In order to use HTTP API -> Endpoint -> Post/train, the rasa nlu data format should be in yaml format. I have followed the instruction in this link
https://rasa.com/docs/nlu/http/. However, I have a problem that there is a pattern like this in the flu training data.
- i want to find a [moderately](price:moderate) priced restaurant and it should serve [polynesian](cuisine) food
The : represent a meaning in yaml file. Does anyone know how can i solve the problem so there is no error?
