Odometry 'Odometry' contains unnormalized quaternions.

[DongHappyyy]

Thank you for your excellent work, which has benefited us a lot. We have successfully run your code and tested it using the DSEC dataset. However, when using the data we collected ourselves, there were instances of mapping failure and warnings. I would like to seek your help. The warning is the following:
[ WARN] [1711100402.847533518]: Odometry 'Odometry' contains unnormalized quaternions. This warning will only be output once but may be true for others; enable DEBUG messages for ros.rviz.quaternions to see more details.
