Isochrone API Call not returning geometry of intersections

[fftg97]

Here's what I did

dist = [600, 900]

core_stations = [[1.147316,51.804177],[1.258808,51.931259]]

body = {"locations":core_stations, "range": dist,"attributes":["area"],"intersections":"true","range_type":"time"}

headers = {
    'Accept': 'application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8',
    'Authorization': '5b3ce3597851110001cf6248103d3b27049f428c96218da1f0f3ae77',
    'Content-Type': 'application/json; charset=utf-8'
}
call = requests.post('https://api.openrouteservice.org/v2/isochrones/driving-car', json=body, headers=headers)

Here's what I got

Here's what I was expecting

I would only expect 4 features to be output, one for each combination of distance and core_station.

Instead there is a 5th feature which has no geometry value.

This only appears to happen for some combinations of locations and distances.

When running this via the web API test it creates a blank map.

Here's what I think could be improved

Thanks for reaching out! Indeed, this looks like a bug to me. Please note that because your query specifies "intersections":"true" the response is expected to contain not only polygons describing the isochrones, but also ones corresponding to their intersections. As there is overlap between some of the isochrone I would expect this to be reflected in the response too.
