Assertion `infos.HasMember("route_summary")' failed

Once the TSP is solved, the -g flag basically triggers a viaroute request to OSRM with the ordered locations. The mentioned assertion prevents the execution to go on when the json response of this viaroute query doesn't contain the required key (used to retrieve timing and distance information).

Try to track the corresponding request in osrm-routed logs and see if the 'route_summary' key is present when used in a browser or with curl.

Alternatively, you can try to spot unexpected values by checking the content of variables query and json_response appearing in https://github.com/jcoupey/vroom/blob/master/src/loaders/osrm_wrapper.h#L247-L253.

Got it...

--max-viaroute-size needs to be set when running osrm-routed.

Thanks for the help. :)

Oh yes, didn't spot you mentioned the --max-matching-size and not the --max-viaroute-size parameter.

Rather than just stopping with the assertion, we should display the error message from OSRM to make it clear what went wrong. This will have to wait a little since all status codes and messages are bound to change in the new server API as of OSRM v5.
