When a player joined the server i get an error in the console:

17.07 06:22:12 [Server] WARN [Essentials] Task #1723 for Essentials v2.17.0.3 generated an exception 17.07 06:22:12 [Server] INFO java.lang.NullPointerException: null 17.07 06:22:12 [Server] INFO at com.earth2me.essentials.xmpp.XMPPManager.updatePresence(XMPPManager.java:146) ~[?:?] 17.07 06:22:12 [Server] INFO at com.earth2me.essentials.xmpp.EssentialsXMPP.updatePresence(EssentialsXMPP.java:113) ~[?:?] 17.07 06:22:12 [Server] INFO at org.bukkit.craftbukkit.v1_13_R2.scheduler.CraftTask.run(CraftTask.java:84) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:22:12 [Server] INFO at org.bukkit.craftbukkit.v1_13_R2.scheduler.CraftScheduler.mainThreadHeartbeat(CraftScheduler.java:449) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:22:12 [Server] INFO at net.minecraft.server.v1_13_R2.MinecraftServer.b(MinecraftServer.java:1010) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:22:12 [Server] INFO at net.minecraft.server.v1_13_R2.DedicatedServer.b(DedicatedServer.java:439) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:22:12 [Server] INFO at net.minecraft.server.v1_13_R2.MinecraftServer.a(MinecraftServer.java:940) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:22:12 [Server] INFO at net.minecraft.server.v1_13_R2.MinecraftServer.run(MinecraftServer.java:837) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:22:12 [Server] INFO at java.lang.Thread.run(Thread.java:748) [?:1.8.0_161]

When a player left the server i also get an error in the console:

17.07 06:41:36 [Server] WARN [Essentials] Task #6731 for Essentials v2.17.0.3 generated an exception 17.07 06:41:36 [Server] INFO java.lang.NullPointerException: null 17.07 06:41:36 [Server] INFO at com.earth2me.essentials.xmpp.XMPPManager.updatePresence(XMPPManager.java:142) ~[?:?] 17.07 06:41:36 [Server] INFO at com.earth2me.essentials.xmpp.EssentialsXMPP.updatePresence(EssentialsXMPP.java:113) ~[?:?] 17.07 06:41:36 [Server] INFO at org.bukkit.craftbukkit.v1_13_R2.scheduler.CraftTask.run(CraftTask.java:84) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:41:36 [Server] INFO at org.bukkit.craftbukkit.v1_13_R2.scheduler.CraftScheduler.mainThreadHeartbeat(CraftScheduler.java:449) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:41:36 [Server] INFO at net.minecraft.server.v1_13_R2.MinecraftServer.b(MinecraftServer.java:1010) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:41:36 [Server] INFO at net.minecraft.server.v1_13_R2.DedicatedServer.b(DedicatedServer.java:439) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:41:36 [Server] INFO at net.minecraft.server.v1_13_R2.MinecraftServer.a(MinecraftServer.java:940) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:41:36 [Server] INFO at net.minecraft.server.v1_13_R2.MinecraftServer.run(MinecraftServer.java:837) ~[patched_1.13.2.jar:git-Paper-634] 17.07 06:41:36 [Server] INFO at java.lang.Thread.run(Thread.java:748) [?:1.8.0_161]
