VirtualWorkbench

I want to use the workbench GUI with command.
However, by all means error　To appear :/
a lot code is https://forums.pmmp.io/threads/open-crafting-table-code.88 I borrowed from.

PHP:

    public function onCommand(CommandSender $sender, Command $command, $label, array $args)
    {
      //Messages
      $Mes1 = "§eYou opened";
      $Mes2 = "§a/vr §7 §8[ §aenchant§8 | §afurnace§8 | §astand§8 | §aworkbench§8 ] ";
      $x = $sender->getX();$y = $sender->getY();$z = $sender->getZ();
      $le = $sender->getLevel();

        if($sender instanceof Player) {
            switch ($command->getName()) {
                case "vr":
                    if (isset($args[0])) {
                        switch (strtolower($args[0])) {
                            case "workbench":
                            $table = $this->getServer()->getLevelByName($le)->getTile(new WindowInventory($sender, 9))->getInventory();
                                $sender->sendMessage($Mes1);
                                $sender->addWindow($table);
                                break;


Since the code after this is not necessary for the question, I will not write it...

 

I think, that you need send workbench to player.
This code allow to create fake chest:

PHP:

$block = Block::get(54);
$block->x = floor($sender->x);
$block->y = floor($sender->y)-2;
$block->z = floor($sender->z);
$block->level = $sender->level;
$sender->level->sendBlocks([$sender],[$block]);

$nbt = new CompoundTag('', [
    new ListTag('Items', []),
    new StringTag('id', $id = Tile::CHEST),
    new IntTag('x', floor($sender->x)),
    new IntTag('y', floor($sender->y) - 2),
    new IntTag('z', floor($sender->z))
]);
/** @var Chest $tile */
$tile = Tile::createTile('Chest', $sender->chunk, $nbt);

$customInv = new ChestInventory($tile);
$sender->addWindow($customInv);
