$pos = new Vector3($player->x,$player->y,$player->z);
    $chest = Tile::createTile(Tile::CHEST,$player->getLevelNonNull(),TileChest::createNBT($pos, null, null, $player));
    $inventory= new ChestInventory($chest);
    $player->addWindow($inventory);
    $inventory->onOpen($player);
            $pk = new ContainerOpenPacket();
    $pk->windowId = $player->getWindowId($inventory);
    $pk->type = WindowTypes::MINECART_CHEST;
    $pk->x = $pk->y = $pk->z = 0;
    $pk->entityUniqueId = $player->getId();
    $player->dataPacket($pk);

What's wrong with this string of code.

This happens because the client thinks there isn't any text on the sign and opens the sign editing UI. This happens because the item NBT isn't added properly.
