addPolyline with overview_polyline

When I get:

"overview_polyline"

from service:

directionsService

I want to put it in my:

addPolyline

in the following way

    this.map.addPolyline({
          'path': response.routes[0].overview_polyline,
          'color': '#000000',
          'width': 3,
          'geodesic': true
        });

but it marks me the error since path is not recognized inaddPolyline
