[6099] Unable to compute a distance/duration matrix

openrouteservice
1

Hi,

Great API, with the R interface this works like a charm. However, I am computing lots of 50x50 duration matrices by car in French municipalities, and I stumbled on this [6099] error in a particular one. I understand that this means that the routing algorithm failed on one of the origin/destination pair. However I don’t know how to debug it and identify the faulty pair without throwing 2500 requests and see which one fails. How would you proceed to debug such a situation ?

These computations are meant to approximate expected travel times within municipalities by averages between randomly draws pairs of points. Since the points are drawn at random, it happens that some of them are disconnected from the general network, e.g. in a military base or a closed car racing circuit. But usually when this happens the matrix is still returned, just with missing/zero distances for the faulty line or column. This is the first time that the computation completely failed. I cannot figure out why and how to fix the request.

Here are the points which broke the API:

Hi,
I will take a look at this. Give me a few days.

Hi,

Ok, thank you very much. If it can help, I tried with another sample and it worked like a charm, so it must be one of these specific points that fails.

I’ve attached a sample that works if it can help figure out what went wrong with the first.

Best
Morgan

Hey Morgan,
can you provide a working api query sample for me? It does not matter if the result works, just that I can actually use it to query the server.
Thanks
