Add Chest Tile

Hey, I'm trying to make a chest UI but I get this error:

This is my code:

PHP:

                $block = Block::get(54);
                $sender->getLevel()->setBlock(new Vector3($sender->getX(), $sender->getY() - 2, $sender->getZ()), $block, true, true);
                $nbt = new CompoundTag("", [
                    new ListTag("Items", []),
                    new StringTag("id", Tile::CHEST),
                    new IntTag("x", floor($sender->getX())),
                    new IntTag("y", floor($sender->getY() ) - 2),
                    new IntTag("z", floor($sender->getZ()))
                ]);
                $nbt->Items->setTagType(NBT::TAG_Compound);
                $tile = Tile::createTile("Chest", $sender->getLevel(), $nbt);
                $i = $tile->getInventory();
                $i->addItem(Item::get(Item::STONE, 0, 1));
                $sender->addWindow($tile->getInventory());

When i delete the line causing the crash I just hear the sound and that's it.

 

You will need to get that ListTag via the Method Provided in $nbt ( i think it's getListTag() ), not through dynamic access

 

use
$nbt->getTag("Items")->setTagType......

 

You don't even need that, getTag takes an class path as second parameter, so getTag("Items", ListTag::class) should work too
