Error when trying to access my LFG page

I get following error message when trying to access my game's LFG page (either from LFG listing or from game's details page). I can access my other game's LFG page so it is not due to my setup. NoMethodError: undefined method `[]' for nil:NilClass Link to my game: <a href="https://app.roll20.net/lfg/listing/42278/deedeesuo" rel="nofollow">https://app.roll20.net/lfg/listing/42278/deedeesuo</a>...
