[6099] Unable to compute distance/duration matrix foot-walk

openrouteservice
1

Hi, I’ve been using the matrix endpoint but am experiencing a 6099 “Unable to compute a distance/duration matrix.” error with certain coordinates and walking mode. For example this fails with the 6099 error:

curl --location --request POST 'https://api.openrouteservice.org/v2/matrix/foot-walking' \ --header 'Authorization: <KEY>' \ --header 'Content-Type: application/json' \ --data-raw '{"locations": [[-3.227298693697719,51.97143087679216],[-3.228480761471288,51.96048889326853]], "metrics": ["distance", "duration"], "sources": [0], "units": "km"}'

But as a standard route it works fine:
https://api.openrouteservice.org/v2/directions/foot-walking?start=-3.227298693697719,51.97143087679216&end=-3.228480761471288,51.96048889326853&api_key=

Any pointers appreciated.

Hey,

I can indeed reproduce your issue. However, when running ors locally and issuing the same command, it somehow works:

$ curl --location \
       --request POST 'http://localhost:8082/ors/v2/matrix/foot-walking' \
       --data-raw '{"locations": [[-3.227298693697719,51.97143087679216],[-3.228480761471288,51.96048889326853]], "metrics": ["distance", "duration"], "sources": [0], "units": "km"}' 
$                                      
{"durations":[[0.0,1393.63]],
 "distances":[[0.0,1.94]],
 "destinations":[{"location":[-3.227349,51.971397],"snapped_distance":5.08},{"location":[-3.22845,51.960504],"snapped_distance":2.68}],
 "sources":[{"location":[-3.227349,51.971397],"snapped_distance":5.08}],
 "metadata":{"attribution":"openrouteservice.org, OpenStreetMap contributors","service":"matrix","timestamp":1670946472683,"query":{"locations":[[-3.227298693697719,51.97143087679216],[-3.228480761471288,51.96048889326853]],"profile":"foot-walking","responseType":"json","sources":["0"],"metrics":["distance","duration"],"units":"km"},"engine":{"version":"6.8.0","build_date":"2022-12-13T15:40:53Z","graph_date":null}}
}

However, the data returned differs quite a bit from the data returned by the directions-request:

{"distance":1628.4,"duration":1172.5}

I am indeed a bit stumped, I’ll open an issue for this.

Best regards

In case it helps, I have experienced the same issue since last week. The matrix API keeps working for ‘cycling-regular’ and ‘driving-car’ but not for ‘foot-walking’. I also attach the whole trace:

As alternative option I am using Directions API for ‘foot-walking’ queries. Thanks in advance.
