Error when providing Odometry to cartographer-ros

Hello developers,

I'm facing an issue while running the cartographer on my own .bag file. I saw in the documentation that I had to remap to allow the cartographer to use the topics from my recorded datas, so I edited both Lua and Launch file.

The error is : Check failed: frame_id[0] != '/' ('/' vs. '/') The frame_id /base_link_orig should not start with a /. See 1.7 in, it appeared when I wrote the remap from the odom topic.

The thing that I don't understand is that I didn't write anything starting by '/'

  • My lua file :

map_builder = MAP_BUILDER, trajectory_builder = TRAJECTORY_BUILDER, map_frame = "map", tracking_frame = "imu", published_frame = "base_link", odom_frame = "odom", provide_odom_frame = true, publish_frame_projected_to_2d = false, use_pose_extrapolator = true, use_odometry = true, use_nav_sat = false, use_landmarks = false, num_laser_scans = 1, num_multi_echo_laser_scans = 0, num_subdivisions_per_laser_scan = 1, num_point_clouds = 2, lookup_transform_timeout_sec = 0.2, submap_publish_period_sec = 0.3, pose_publish_period_sec = 5e-3, trajectory_publish_period_sec = 30e-3, rangefinder_sampling_ratio = 1., odometry_sampling_ratio = 1., fixed_frame_pose_sampling_ratio = 1., imu_sampling_ratio = 1., landmarks_sampling_ratio = 1.,
