I have a packet that goes to the client in my code, that the server is for some reason trying to load... This causes a crash with this error:

[19:41:39] [Server thread/ERROR] [minecraft/MinecraftServer]: Encountered an unexpected exception
net.minecraftforge.fml.LoadingFailedException: Loading errors encountered: [
	Laser Mod (lasermod) encountered an error during the common_setup event phase

Here is where I reference a ClientWorld in my code:

public static void handle(PacketLaserLensUpdate message, Supplier<NetworkEvent.Context> ctx) {
    ctx.get().enqueueWork(() -> DistExecutor.runWhenOn(Dist.CLIENT, () -> () -> {
        World world = Minecraft.getInstance().world;
        TileEntity te = world.getTileEntity(message.pos);
        if (te instanceof LaserTileEntity) {
            LaserTileEntity laser = (LaserTileEntity) te;
            laser.color = message.color;
            laser.direction = message.direction;
            laser.maxDistance = message.distance;
            laser.thickness = message.thickness;
            laser.active = message.active;
        }
    }));
    ctx.get().setPacketHandled(true);
}

As you can see I tried using DistExecutor, but that isn't working for some reason. Im registering the packets in the FMLCommonSetupEvent.

Weirdly, when I inline the World in this part of the code

World world = Minecraft.getInstance().world;
TileEntity te = world.getTileEntity(message.pos);

the error disappears... But that isn't really a fix to the problem, as in some situations, inlining might not be possible.
What can I do to fix this error without inlining?

That worked fine, and thanks for the info about DistExecutor.
