If I use the following parameters in the the url, then it works fine, both start and end point will be set.
But in some cases I only want to preset the start point, and the user has to fill in the end point himself on https://maps.openrouteservice.org/, but no matter what I try I can’t get it to work. I tried leaving the second set of coordinates empty, or just fill it with a space.
I suspect this is not possible, right? If it is, how would I make it work?
