I've debug this one a bit. Since thiis plugin is converting every single fields it's not working of the content of the field is not a string. Thus it's failing on my side, because the field _discoverable is a bool and jinja is failing to process the data.

I'm not sure how to work around this one without changing the implementation to process only the body field or a fixed list of fields.

Closing, I was using version 0.2 on python2.7. I've upgrade to version 0.3 on python3
