Map İmage

I put a picture on the map but when in game the map invisible

Code:

Code:

        
        $r = 0;
        $g = 0;
        $b = 0;
        $ancho = 128;
        $altura = 128;
        $map = Item::get(Item::FILLED_MAP);
        $map->setCount(1);
        $imagen = imagescale($imagen, $ancho, $altura, IMG_NEAREST_NEIGHBOUR);
        imagepng($imagen, $folder."map-new.png");
        for($y = 0; $y < $altura; ++$y){
            for($x = 0; $x < $ancho; ++$x){
                $color = imagecolorsforindex($imagen, imagecolorat($imagen, $x, $y));
                $r = $color["red"];
                $g = $color["green"];
                $b = $color["blue"];
                $colores[$y][$x] = new Color($r, $g, $b);
            }
        }
        $key = 18293883;
        $tag = new CompoundTag("", []);
        $tag->setTag(new StringTag("map_uuid", $key));
        $map->setCompoundTag($tag);
        $p->getInventory()->setItem(6, $map);
        $pk = new ClientboundMapItemDataPacket();
        $pk->mapId = $key;
        $pk->type = ClientboundMapItemDataPacket::BITFLAG_TEXTURE_UPDATE;
        $pk->height = 128;
        $pk->width = 128;
        $pk->scale = 1;
        $pk->colors = $colores;
        $p->dataPacket($pk);

 

map_uuid is a LongTag not StringTag
