Telegram channel markdown syntax problem

Rasa version: rasa 1.0.9 rasa-core 0.13.7 rasa-core-sdk 0.13.0 rasa-sdk 1.0.0

Rasa X version (if used & relevant): rasa-x 0.19.0

Python version: Python 3.6.8

Operating system (windows, osx, …): Windows 10

Issue: Seems default telegram connector doesn’t support markdown syntax

Command OR request that led to error:

1. Add to action.py or domain.yml text with url in markdown syntax
2. Check your action/template in bot

Result: You: test Bot: test link: [test](https://rasa.com/)

Expected result: You: test Bot: test link: test

Content of configuration file (actions.py) (if relevant):

dispatcher.utter_message('test link: [test](https://rasa.com/')

Content of domain file (domain.yml) (if relevant):

  utter_test_url:
    - text: "test link: [test](https://rasa.com/)"

@selphe it’s possible that the change to self.send_message(recipient_id, message_part, **kwargs) will be default, we’ll have to think about how this would affect the channels we already have. If we did change that then we could set the default to markdown because you could still pass HTML by declaring it.

However, as I said, i’m wary about doing that because of other channels ending up failing with got unexpected keyword argument "parse_mode".

If you’d like to customize your text message, perhaps an even better workaround is using custom output payloads to specify your api call directly. E.g.

utter_test_url:
    - custom: 
       text: "test link: [test](https://rasa.com/)"
       parse_mode: markdown

or via

dispatcher.utter_custom_json('test link: [test](https://rasa.com/', parse_mode='markdown')

Sorry, of course, thanks for the fix! Yes it’s a json payload so it definitely needs to be everything inside the curly braces as you have it. 🙂 was a little late for me 😅 glad you are able to customize the message without changing the source code. That’s why we added the custom functionality in the first place! 😃
