> I am still seeing errors when accessing an individual tserver page (e.g. /tservers?s=<tserver address>). There might be a few things to remove still from server.js and server.ftl that is in the scope of this PR but I am not certain that its the same thing that is being addressed with the other changes in this PR. I tried running this locally and looking at a page for a tserver and it failed. Looked in the monitor log and saw the following. Tracing this back I suspect the cause may be this [line](https://github.com/apache/accumulo/blob/0f5984d769afe3c08f0b2704f50ab9aed5045c43/server/tserver/src/main/java/org/apache/accumulo/tserver/TabletStatsKeeper.java#L77) where `null` is passed in for the split into (looked at 3.1 and it always passes some object). Could try passing in a `new ActionStats()` obj there for the split info and see if that fixes, if it does can open a follow on issue about fixing the tserver code. Not sure why its passing null in there all the time, probably a bug introduced by removing bulk import and/or compaction code from the tserver. ``` 2024-10-28T21:41:36,576 [server.HttpChannel] WARN :
