Tons of Error: Couldn't pass PlayerResourcePackStatusEvent

[Trard]

I have the latest version and almost every time player connects there is an error like this:

[12:00:41] [ForcePack - Task Executor #1622/ERROR] [com.velocitypowered.proxy.event.VelocityEventManager]: Couldn't pass PlayerResourcePackStatusEvent to forcepack 1.3.71 java.util.ConcurrentModificationException: null at java.base/java.util.HashMap$KeySpliterator.tryAdvance(HashMap.java:1739) ~[?:?] at java.base/java.util.stream.ReferencePipeline.forEachWithCancel(ReferencePipeline.java:147) ~[?:?] at java.base/java.util.stream.AbstractPipeline.copyIntoWithCancel(AbstractPipeline.java:588) ~[?:?] at java.base/java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:574) ~[?:?] at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:560) ~[?:?] at java.base/java.util.stream.MatchOps$MatchOp.evaluateSequential(MatchOps.java:230) ~[?:?] at java.base/java.util.stream.MatchOps$MatchOp.evaluateSequential(MatchOps.java:196) ~[?:?] at java.base/java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:265) ~[?:?] at java.base/java.util.stream.ReferencePipeline.anyMatch(ReferencePipeline.java:672) ~[?:?] at com.convallyria.forcepack.velocity.handler.PackHandler.isWaitingFor(PackHandler.java:76) ~[?:?] at com.convallyria.forcepack.velocity.listener.ResourcePackListener.onPackStatus(ResourcePackListener.java:54) ~[?:?] at com.convallyria.forcepack.velocity.listener.Lmbda$23.execute(Unknown Source) ~[?:?] at com.velocitypowered.proxy.event.UntargetedEventHandler$VoidHandler.lambda$buildHandler$0(UntargetedEventHandler.java:56) ~[velocity5.jar:3.4.0-SNAPSHOT (git-876b9c36-b465)] at com.velocitypowered.proxy.event.VelocityEventManager.fire(VelocityEventManager.java:677) ~[velocity5.jar:3.4.0-SNAPSHOT (git-876b9c36-b465)] at com.velocitypowered.proxy.event.VelocityEventManager.lambda$fire$5(VelocityEventManager.java:542) ~[velocity5.jar:3.4.0-SNAPSHOT (git-876b9c36-b465)] at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1144) ~[?:?] at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:642) ~[?:?] at java.base/java.lang.Thread.run(Thread.java:1575) [?:?]

I use velocity

This error doesn’t make any sense

Are you using the latest commit (NOT version)?

[Trard]

I don't. I use the latest release version https://github.com/SamB440/ForcePack/releases/tag/1.3.71

[SamB440]

Please use the latest commit

It's in combined/build/libs/forcepack-1.3.71-spigot-velocity.jar

https://github.com/SamB440/ForcePack/actions/runs/14624777661/artifacts/2996184132

[Trard]

I will try. Thanks

I tried updating and there is the same error again

It doesn't seem to break anything, but it's hard to read the logs with this error basically everywhere.

Are you using any plugins on your proxy? I’ve never seen this error and nobody else has reported it so I can only assume it’s a compatibility issue with another plugin

[Trard]

Are you using any plugins on your proxy? I’ve never seen this error and nobody else has reported it so I can only assume it’s a compatibility issue with another plugin

Yes. Here are plugins:

• forcepack-1.3.71-spigot-velocity
• LuckPerms-Velocity-5.4.141
• SkinsRestorer
• limboapi-1.1.27-SNAPSHOT
• limboauth-1.1.14
• minimotd-velocity-2.1.5
• voicechat-velocity-2.5.20

I guess it might be compatibility issue with limboapi. (But I am not sure) Also there is a config line that might be relevant, but I don't know if ForcePack modify any packets.

# Enable if you are using plugins that modify packets. (e.g. ViaVersion, Raknetify or PacketEvents)
# Require 'save-uncompressed-packets: true' to work properly
compatibility-mode: false

Same problem here

[SamB440]

Same problem here

That doesn't really help, do you share any of the plugins they mentioned?

[gummiangler]

@SamB440 I have these plugins

yes, i have viaversion, but the error occured before installing viaversion too
