trying autoware lane change but op_local_planner m_TrajectoryCosts.size() Not Equal m_GeneratedRollOuts.size() error

edit

in Autoware kinetic 1.13 ver, i want to enable lane change using op_global_planner, op_local_planner

i set all enableLaneChange parameter so lane_waypoints_array topic send multi lane global path to op_local_planner

but the code in op_behavior_selector and op_trajectory_evaluator's callbackGetLocalPlannerPath

if(globalPathId_roll_outs == globalPathId)

globalPathId_roll_outs is always last rollout's gid and globalPathId is always first global path's gid

so, that if condition never set true and it caused m_GlobalPathsToUse has no data -> DoOneStep function makes error : m_TrajectoryCosts.size() Not Equal m_GeneratedRollOuts.size() error

i think it has some bug

because, if we want to lane change, op_global_planner makes multi global path and they have own gid (if 3 lanes in global path, gid is 0, 1, 2)

how can i revised it?
