getHomes() nullptrexception

[MineWarz]

Hi,

If this is the wrong place to bring this up, please direct me to where I can ask about it.

We're hosting a minecraft server since a month ago, and we have Dynmap and EssentialsX setup. We also use Dynmap-EssentialsX, mostly just to show our player homes on Dynmap.
However, ever since about two weeks ago, our console is being spammed with a nullptr exception every minute or so, and homes do not show up on the Dynmap anymore (save for one apparently, which has the wrong icon).

We get the following error message:
java.lang.NullPointerException: Cannot invoke "com.earth2me.essentials.User.getHomes()" because "user" is null at me.kingtux.dynmapessentials.DynmapEssentials.runHomes(DynmapEssentials.java:110) ~[DynmapEssentials-1.2.jar:?] at me.kingtux.dynmapessentials.DynmapEssentials.run(DynmapEssentials.java:70) ~[DynmapEssentials-1.2.jar:?] at org.bukkit.craftbukkit.v1_19_R3.scheduler.CraftTask.run(CraftTask.java:101) ~[paper-1.19.4.jar:git-Paper-510] at org.bukkit.craftbukkit.v1_19_R3.scheduler.CraftScheduler.mainThreadHeartbeat(CraftScheduler.java:483) ~[paper-1.19.4.jar:git-Paper-510] at net.minecraft.server.MinecraftServer.tickChildren(MinecraftServer.java:1483) ~[paper-1.19.4.jar:git-Paper-510] at net.minecraft.server.dedicated.DedicatedServer.tickChildren(DedicatedServer.java:447) ~[paper-1.19.4.jar:git-Paper-510] at net.minecraft.server.MinecraftServer.tickServer(MinecraftServer.java:1397) ~[paper-1.19.4.jar:git-Paper-510] at net.minecraft.server.MinecraftServer.runServer(MinecraftServer.java:1174) ~[paper-1.19.4.jar:git-Paper-510] at net.minecraft.server.MinecraftServer.lambda$spin$0(MinecraftServer.java:320) ~[paper-1.19.4.jar:git-Paper-510] at java.lang.Thread.run(Thread.java:833) ~[?:?]

There seems to be a player/entity that is being invoked but is null every time. I looked into corrupt player data, but couldn't find anything. We have tried restarting the server, updating/reinstalling the plugins, even removing everyone's homes in the essentials playerdata. Nothing has worked so far. I also cannot really find anything about this issue online. Does anyone know if this is a bug and how we can resolve it?
