If it's logic the prob come from this i think : at de.codecrafter47.data.sponge.sponge5.Sponge5.getPrimaryGroup(Sponge5.java:26) ~[Sponge5.class:?]

Version :

• spongeforge-1.12.2-2705-7.1.0-BETA-3206.jar
• LuckPerms-Sponge-4.2.42.jar

Which version of BungeeTabListPlus_SpongeBridge are you using? If it's an old version (e.g. from last year) the issue can probably be fixed by updating to the latest version.

[Yann151924]

I use the latest release 2.8.4.

[CodeCrafter47]

I just tested these versions and it works just fine. Can you use the /sponge plugins bungeetablistplus command and see whether you get the desired output:

> sponge plugins bungeetablistplus 
[13:41:02] [Server thread/INFO] [minecraft/DedicatedServer]: BungeeTabListPlus-SpongeBridge v2.8.4
    ID: bungeetablistplus
    Main class: codecrafter47.bungeetablistplus.spongebridge.SpongePlugin

[Yann151924]

I re-tested with the last version 2.8.8 but i have the same error, i don't know if the prob come from this :

        if (!classExists("org.spongepowered.api.service.permission.SubjectReference")) {
            addProvider(MinecraftData.Permissions_PermissionGroup, Sponge5::getPrimaryGroup);
        } else {
            addProvider(MinecraftData.Permissions_PermissionGroup, Sponge7::getPrimaryGroup);
        }

In your data library you check if the class exist but the class exist in sponge7, so the plugin use the sponge5 which cause the spam i think.

[CodeCrafter47]

That code has been replaced with an actual version check a long time ago: https://github.com/CodeCrafter47/minecraft-data-api/commit/24f707e6a84b1f0e74b5e5ab3db5b8e215e6c464. The fix is present in version 2.8.8 of the SpongeBridge.

[Yann151924]

Woops my bad, so i don't know where the prob is, but it seems the plugin want to use the sponge5 class :(
