My markup doesn't work

Hello there schema.org <http://schema.org/>,

i am having a really hard time making my structured data markup work.

I am trying to mark our pages for events but still no results in google rich snippets (serp for « event »  + town) 

Example : https://yurplan.com/event/Lyon-Biere-Festival-2/13483 <https://yurplan.com/event/Lyon-Biere-Festival-2/13483> for Lyon, France

Where would be the right place to ask for help ?
