Error after /wb bypasslist

[TheNety]

Hi, I'm getting this error in command /wb bypasslist

16:57:05 WARN: at com.wimbli.WorldBorder.UUID.UUIDFetcher.getName(UUIDFetcher.java:128) 16:57:05 WARN: at com.wimbli.WorldBorder.UUID.UUIDFetcher.getNameList(UUIDFetcher.java:145) 16:57:05 WARN: at com.wimbli.WorldBorder.cmd.CmdBypasslist$1.run(CmdBypasslist.java:45) 16:57:05 WARN: at org.bukkit.craftbukkit.v1_13_R2.scheduler.CraftTask.run(CraftTask.java:84) 16:57:05 WARN: at org.bukkit.craftbukkit.v1_13_R2.scheduler.CraftScheduler.mainThreadHeartbeat(CraftScheduler.java:449) 16:57:05 WARN: at net.minecraft.server.v1_13_R2.MinecraftServer.b(MinecraftServer.java:1010) 16:57:05 WARN: at net.minecraft.server.v1_13_R2.DedicatedServer.b(DedicatedServer.java:439) 16:57:05 WARN: at net.minecraft.server.v1_13_R2.MinecraftServer.a(MinecraftServer.java:940) 16:57:05 WARN: at net.minecraft.server.v1_13_R2.MinecraftServer.run(MinecraftServer.java:837) 16:57:05 WARN: at java.lang.Thread.run(Thread.java:745)

And instead of my name I see "null".

The bypass list is stored as a list of player UUIDs, since player names can be changed while UUIDs are the unique account ID which never changes. When it needs to check the player name associated with a given UUID (done once per server start and then cached), it checks that with the Mojang server.

The error you're getting is with it trying to check the stored UUID with Mojang's server for the associated player name, and that is failing for some reason.

You might try "/wb bypass null off" to try to remove that bypass, then "/wb bypass [your_player_name] on" to add yourself back to the bypass list. Then restart the server and run "/wb bypasslist" again to see if that fixed it.

If the problem persists, could you provide me with your player name so I can test it? I've just re-tested with my player name and another and couldn't find any problem.

Well, "/wb bypass null off" doesn't remove the null from bypass list. But from what you said, it could be because the not working username is not premium version of minecraft and the server is in offline-mode?

[Brettflan]

Well yeah, an old (now unsupported by Mojang) demo-mode account will not work.

[TheNety]

Oh.. And you're not going to add possibility to make it work, right?

[Brettflan]

Sorry, but the UUID method is safer (prevents potential name spoofing for permission/OP escalation) and works regardless of whether the player changes their name.

I also have no interest whatsoever in making changes or adding features which have practically no purpose but facilitating piracy.
