Help with config + servers

[afunu]

I made a config in my 1.16.5 minecraft mod, and I register it by doing:

ModLoadingContext.get().registerExtensionPoint(
                        ExtensionPoint.CONFIGGUIFACTORY,
                        () -> (mc, screen) -> new ModConfig()
                );

but when I try to run the mod with a server I get:
Attempted to load class net/minecraft/client/gui/screen/Screen for invalid dist DEDICATED_SERVER

I tried to add:

 DistExecutor.safeRunWhenOn(Dist.CLIENT, () -> () -> {
                ModLoadingContext.get().registerExtensionPoint(
                        ExtensionPoint.CONFIGGUIFACTORY,
                        () -> (mc, screen) -> new ModConfig()
                );
            });

or even:

if (FMLLoader.getDist() == Dist.CLIENT) {
            DistExecutor.safeRunWhenOn(Dist.CLIENT, () -> () -> {
                ModLoadingContext.get().registerExtensionPoint(
                        ExtensionPoint.CONFIGGUIFACTORY,
                        () -> (mc, screen) -> new ModConfig()
                );
            });
        }

but that still gives me the error. also, for some reason, if I do this:
 

private static void method() {
        if (FMLLoader.getDist() == Dist.CLIENT) {
            ModLoadingContext.get().registerExtensionPoint(
                    ExtensionPoint.CONFIGGUIFACTORY,
                    () -> (mc, screen) -> new ModConfig()
            );
        }
    }

without calling the "method" method, it still gives me the error.

Thanks.

You have to move the method call #registerExtensionPoint into a separate class, because the Function within the Supplier accepts a Screen object, whereby you load the Screen class, which then causes the error.

ModLoadingContext.get().registerExtensionPoint(ExtensionPoint.CONFIGGUIFACTORY, () -> (mc, screen) -> new ModConfig());
