public final class Main extends JavaPlugin {

    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(new listener(), this);

    }

    @Override
    public void onDisable() {

    }
}

I am very new to java development regarding minecraft and I have no idea how to fix this and I would like some suggestions on what the issue could be. The plugin itself is functional in-game but the command just doesn't work, I'm suspecting that

public static @NotNull String getInstance() {

        return "";
    }

public static @NotNull String getInstance() {

        return "";
    }

might have a part in this issue but I do not know how it works or what to put in there. I also tried using the suggestions with the ''getInstance'' issue in the public class drill which had suggested me that part of the code.

can you show the error stacktrace that happens when it says unexpected error occurred

hiiOP•2w ago

Console?

message.txt

ayylmao123xdd•2w ago

it says the namespace is invalid and it doesnt follow the regex

hiiOP•2w ago

So I can't use spaces?

ayylmao123xdd•2w ago

try "a" and check if the error is different

hiiOP•2w ago

Works.

ayylmao123xdd•2w ago

once you run it

hiiOP•2w ago

The issue is fixed.
