Rasa core button use issue

When using below button option in template getting unicode error: File “_ruamel_yaml.pyx”, line 904, in _ruamel_yaml.CParser._parse_next_event ruamel.yaml.parser.ParserError: while parsing a block collection in “”, line 90, column 9 did not find expected ‘-’ indicator in “”, line 91, column 9

below is the template configuration. utter_ask_room_type:

  • text: “Please provide your room type” buttons: - title: “economy” payload: “/enter_data{“room_type”:“economy”}” - title: “premium” payload: “/enter_data{“room_type”:“premium”}” - title: “luxury” payload: “/enter_data{“room_type”:“luxury”}”

Look good to me, can you give the indentation of your template too ? (use 4 spaces to display as code)
