Create train data in yaml format using Rasa_NLU_server

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 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?

@cctong-castiel I am not sure I understand what is the issue you are facing? Can you provide the log of the error you are getting?
