[1.16.5] Can't summon entity from mods

[dayd21git]

Minecraft version: 1.16.5 Build version: 1.16.5-9b57815e Mods/Plugins: MrCrayfish's Vehicle, MyPlugin Description: When I try to summon an entity with the standard /summon vehicle:couch command, everything goes well. But if I try to summon an entity with a custom /plug summon vehicle:couch or /plug summon vehicle_couch command, nothing comes out.

Code:

private void summon(CommandSender s, String args[]) {
    if (args.length < 2) return;
    EntityType type;
    try {
        type = EntityType.valueOf(args[1].toUpperCase());
    } catch (IllegalArgumentException | NullPointerException e) {
        return;
    }
    Location loc;
    if ((s instanceof Player)) loc = ((Player)s).getLocation().add(0, 2, 0);
    else {
        if (args.length < 6) return;
        World world = Bukkit.getWorld(args[2]);
        if (world == null) return;
        int x = 0, y = 0, z = 0;
        try {
            x = Integer.parseInt(args[3]);
            y = Integer.parseInt(args[4]);
            z = Integer.parseInt(args[5]);
        } catch (NumberFormatException e) {
            return;
        }
        loc = new Location(world, x, y, z);
    }
    loc.getWorld().spawnEntity(loc, type);
}
