Hi @snack0verflow

I think it is because of the version mismatch. You can read more about it from here.

Hey @vchrombie,
This was while running kibiter alone without elasticsearch. The executable bin/kibana gave this syntax error.

A similar issue has been reported at chaoss/grimoirelab#261. I didn't have time to have a deep look at it. @snack0verflow @vchrombie feel free to dive into it.

Thanks!
