The coordinate order should be inverted

Line 263 in 4f97aee

'coordinates': polyline.decode(route['geometry'])}

polyline.decode returns a list of (latitude, longitude) pairs, however the geojson format uses (longitude, latitude).

Thus calling service.directions() without explicitly set geometries to geojson will return a wrongly formatted geojson.

Line 263 should be:
'coordinates': [(lng, lat) for lat, lng in polyline.decode(route['geometry'])]}

Also noted in #250, which was closed before I saw it. Thanks for the report, @Taxuspt !
