I am passing the following command with almost all default values for the parameters: marouter --route-files ./SUMO/Demand/trips_marouter.trip.xml --net-file ./SUMO/Net/sumo_secondary_filter.net.xml -o ./SUMO/Output/marouter_output.rou.xml --weights.interpolate --paths.penalty 1 --junction-taz --scale 20 --tolerance 0.001 --max-inner-iterations 1000 --paths 5 --route-choice-method logit --weight-attribute traveltime --logit.beta 0.15 --logit.gamma 4 --logit.theta 0.01 --max-iterations 10 --keep-all-routes --weights.priority-factor 10 --routing-algorithm CH --aggregation-interval 3600 --routing-threads 36 --netload-output ./SUMO/Output/netload_Marouter.xml --verbose --ignore-errors --log ./SUMO/Output/Marouter_log.xml I tried multiple versions with fewer options too (which I didn't save) and still I got the response from Dijkstra router.
