Expected behaviour:

I expect template key to work when I set the template (it worked 1 day ago and nothing changed)

Actual behaviour:

Flexget gives me the following error:
2016-12-16 23:42 CRITICAL manager [/templates/telegram_bot/telegram] The key template is not valid here.
2016-12-16 23:42 CRITICAL manager Failed to load config file: Did not pass schema validation.

Steps to reproduce:

Copy my config and run flexget execute

Config:

  telegram_bot:
    telegram:
      bot_token: 123456:botid
      template: |
        {{task}} - Download started:
        {% if series_name is defined %}
        {{tvdb_series_name|d(series_name)}} {{series_id}} {{tvdb_ep_name|d('')}}
        {% elif imdb_name is defined %}
        {{imdb_name}} {{imdb_year}}
        {% else %}
        {{title}}
        {% endif %}
      recipients:
        - username: your-username

Log:
