GeoJSON is not properly formatted

GeoJSON returned by the server is invalid and does not pass lint tests on /france/v1/polygon when specifying a geojson serializer.

Line 7: the first and last positions in a LinearRing of coordinates must be the same Line 75: the first and last positions in a LinearRing of coordinates must be the same Line 359: the first and last positions in a LinearRing of coordinates must be the same Line 659: the first and last positions in a LinearRing of coordinates must be the same Line 1123: the first and last positions in a LinearRing of coordinates must be the same Line 1351: the first and last positions in a LinearRing of coordinates must be the same Line 1395: the first and last positions in a LinearRing of coordinates must be the same Line 6703: the first and last positions in a LinearRing of coordinates must be the same […]

Relevant spec from http://geojson.org/geojson-spec.html#polygon:

A LinearRing is closed LineString with 4 or more positions. The first and last positions are equivalent (they represent equivalent points). Though a LinearRing is not explicitly represented as a GeoJSON geometry type, it is referred to in the Polygon geometry type definition.

@kofronpi we just release an improved version of the geojson feature. could you test it again?

Okay, this is very strange. We are performing this repair operation also on our servers. We will look into this error. Thanks for bringing it up.
