Over a network /scan working but hector_mapping

If you look at /scan topic data the message produced has frame_id: "laser"
You should try to change the following lines
arg name="base_frame" default="base_frame"/>

The values for base_frame and odom_frame should be 'laser'

This worked for me.

In my case the issue was a time difference between two machines.
After installing ntp and starting it, the message went away.

Hi did you fix the problem? recently I also got that error. I guess it is because the rplidar scan points it is not enough. When I changed rplidar scan_mode to 4k, I got the problem. But when the scan_mode is 10k or 16k I did get that error.

I experienced same issue while connecting to wifi network produced by raspberry pi3b. The time on the Pi differed from the time set on the laptop. Adjusting the time and timezone using timedatectl on the Pi resolved the issue. Thanks @IrekRybark .
