It would be best if you could post the logs, as the current information is a bit limited.

  log.Error("fail to split region",
  	logutil.Region(regionInfo.Region),
  	logutil.Key("key", key),
  	zap.Stringer("regionErr", resp.RegionError))

It seems like the previous part should give you some information about the region/key.

This is normal. The lightning task will retry on its own. It might be due to high pressure on the TiDB cluster, causing the region to not split successfully as expected.
