I can’t get API /model/train endpoint working on Rasa 2.0. Even if I copy your example from [Rasa Open Source Documentation](https://rasa.com/docs/rasa/pages/http-api#operation/trainModel) I’m keep getting 500

Running a fresh Rasa 2.0 `rasa init` project

```auto
$ rasa --version
Rasa Version : 2.0.0
Rasa SDK Version : 2.0.0
Rasa X Version : None
Python Version : 3.6.9 (default, Oct 8 2020, 12:12:24)
Operating System : Linux-4.15.0-66-generic-x86_64-with-Ubuntu-18.04-bionic
Python Path : /usr/bin/python3

$ rasa run --enable-api

```

Request copied from docs

Response

```auto
{
    "version": "2.0.0",
    "status": "failure",
    "message": "Ran training, but it finished without a trained model.",
    "reason": "TrainingError",
    "details": {},
    "help": null,
    "code": 500
}

```

and this is in terminal

```auto
No training data given. Please provide stories and NLU data in order to train a Rasa model using the '--data' argument.
2020-10-15 09:40:20 ERROR rasa.server - Ran training, but it finished without a trained model.

```

What’s wrong please?

Hi @mbukovy, thanks for reporting this.

Can you try replacing `nlu:` and `stories:` with a single `data:` key that contains all of the training data together?

I have had the same issue. I am very new to Rasa. I do not understand how to combine nlu and stories with a data key. Appreciate a bit more detail. Thanks

@b-quachtranWell, that didn’t work 🙂

    "message": "To train a Rasa model you need to specify at least one type of training data. Add `nlu` and/or `stories` to the request.",
    "reason": "BadRequest",
    "details": {
        "parameters": [
            "nlu",
            "stories"
        ],

Hi @mbukovy, it appears our documentation is in need of an update to match the YAML spec.

You can use the /model/train endpoint with YAML by setting the request header’s `Content-Type` to `application/x-yaml`. Inside the request body, you’ll pass in a single YAML formatted string containing the configuration, domain definitions, and training data.

For example:

```auto
stories:
- story: My story
  steps:
  - intent: greet
  - action: utter_greet

rules:
- rule: My rule
  steps:
  - intent: greet
  - action: utter_greet

intents:
- greet

nlu:
- intent: greet
  examples: |
   - hi
   - hello
- intent: bye
  examples: |
   - goodbye
   - bye

responses:
  utter_greet:
  - text: Hi

language: en

polices:
   - name: RulePolicy

pipeline:
   - name: WhitespaceTokenizer
   - name: CountVectorsFeaturizer
   - name: DucklingHTTPExtractor
   - name: DIETClassifier
     epochs: 1
```

Thank you @b-quachtran it seems to be working well. And it’s even better then the old json request 🙂

Keep up the great work!
