I need help for module Trafic

[greda]

Hello,
I can not get the traffic module to work. Is it possible to switch to French?
My config :

{
	module: 'MMM-Traffic',
	position: 'top_left',
	classes: 'dimmed medium', //optional, default is 'bright medium', only applies to commute info not route_name
	config: {
		api_key: 'MyApiKey',
		mode: 'driving',
		language: "fr",
		origin: '75013 Paris, France',
		destination: '76000 Rouen, France',
		arrival_time: '0825', //optional, but needs to be in 24 hour time if used.
		route_name: 'Maison vers le bureau',
		changeColor: true,
		showGreen: false,
		limitYellow: 5, //Greater than 5% of journey time due to traffic
		limitRed: 20, //Greater than 20% of journey time due to traffic
		traffic_model: 'pessimistic',
		interval: 120000, //2 minutes
		showWeekend: false,
		allTime: false
	}
},

Thank you for your help.
