Plugin code:

package com.webzyno.medicraft.lobby;

import com.sk89q.worldguard.WorldGuard;
import com.sk89q.worldguard.protection.regions.RegionContainer;
import org.bukkit.plugin.java.JavaPlugin;
import org.slf4j.Logger;

public final class Lobby extends JavaPlugin {

    public final Logger logger = getSLF4JLogger();

    @Override
    public void onEnable() {
        Long startTime = System.currentTimeMillis();

        // configure necessary dependencies and listeners
        RegionContainer container = WorldGuard.getInstance().getPlatform().getRegionContainer();

        Long endTime = System.currentTimeMillis();
        logger.info(String.format("Successfully enabled. (took %dms)", endTime - startTime));
    }

    @Override
    public void onDisable() {
        logger.info("Goodbye!");
    }
}

To Reproduce

1. Just start the server and error will show on the console

Expected behavior

It should correctly get the RegionContainer. But when I dig into the source code of WorldGuard, I found the WorldGuardPlatform in WorldGuard instance is null and cannot pass the null check. Please help me solve the problem.

if this is your plugin, please join discord for help. if it isn't, report it to the developer of that plugin.

in either case this isn't a worldguard bug.

But this is because your API have bug that WorldGuardPlatform cannot be initialized, so WorldGuard cannot successfully invoke getPlatform() method.

WorldGuard itself wouldn't be able to run if that were the case. That's not shown in your log, and the idea that 35k people are currently running a broken version of WorldGuard also seems to dismiss that idea. Again, feel free to ask for help on discord.
