Unable to visualiz pointcloud

[Ayane11]

When I'm using run_patchwork.launch and my own dataset, I want to visualize the "ground" topic in rviz, but it tells me that

Transform [sender=unknown_publisher]
For frame [laser_link]: Fixed Frame [map] does not exist

In the terminal, I saw:
10108th| Time takes 1.02 ms (979.52 Hz). # cloud: 24964 -> 6649
10109th node come
Failed to find match for field 'label'.
Failed to find match for field 'id'.
Operating patchwork...
10109th| Time takes 2.22 ms (450.37 Hz). # cloud: 24887 -> 6545

Failed to find match for field 'id'.

could you help me?

It must due to the frame issue. Could you check the 'Fixed Frame' slot?

[LimHyungTae]

condParam<std::string>(nh, "frame_patchwork", frame_patchwork, frame_patchwork);

And you can assign the specific frame by using that parameter
