New product URL is catalog/category/view

[patryk_wojciechowski]

Hello,

I have migrated my database from Magento 1 to Magento 2.3.3 and everything is working fine, except minicart url's which I edited in filre Defaultitem.php here is the code:

if ($this->item->getRedirectUrl()) {
            return $this->item->getRedirectUrl();
        }

        $product = $this->item->getProduct();
        $option = $this->item->getOptionByCode('product_type');
        if ($option) {
            $product = $option->getProduct();
        }

        $categoryIds = $product->getCategoryIds();
        if (!$categoryIds) {
            return null;
        }
        
        $_category = $this->catmodel->load($categoryIds[0]);
        //return $_category->getUrl();
        return explode('.html', $_category->getUrl())[0] . '/' . $product->getUrlKey() . '.html';

For every *old* product that got migrated from Magento 1 it is working fine I get url like:

http://beta.pneumatig/mycategoryname/subcategory/subcat2/subcat3/wkretarka-cp-10-005-02-nm-1000-obrmin.html <-- product

but Im also dynamically creating new products based on user input and whenever that new product is added to the cart, the following url shows in minicart:

http://beta.pneumatig/catalog/category/view//silownik-profilowy-serii-h-32-325.html <- product

How do I fix that??

Here is my product create function:

$product = $this->productFactory->create();
        $product->setSku($this->_getSku());
        $product->setName($this->_getName());
        $product->setTypeId(\Magento\Catalog\Model\Product\Type::TYPE_SIMPLE);
        $product->setVisibility(4);
        $product->setPrice(strval($this->_cylinderPrice));
        $product->setAttributeSetId(25);
        $product->setStatus(\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);
        $product->setTaxClassId(1);
        //112 = Pneumatig
        $product->setManufacturer(112);
        $product->setCountryOfManufacture('PL');
        
        $product->setDescription('Test opis');
        $product->setShortDescription('Test short opis');
        //Custom atrybuty
        $product->setCustomAttribute('pg_cylinder_dia', $this->getDiameter());
        $product->setCustomAttribute('pg_cylinder_stroke', $this->getStroke());
        $categoryIds = $this->productRepository->get($this->_originalSku);
        $categoryIds = $categoryIds->getCategoryIds();
        
        $product->setCategoryIds([intval($categoryIds[0]), intval($categoryIds[1])]);
        
        $url = preg_replace('#[^0-9a-z]+#i', '-', $this->_getName());
        $url = preg_replace('#x-#i', '', $url);
        $url = strtolower($url);
        $product->setUrlKey($url);

        if (file_exists($this->_getImage())) $product->addImageToMediaGallery($this->_getImage(), array('image', 'small_image', 'thumbnail'), false, false);
        
        //$product->setShortDescription($this->_getImage());
        
        $product = $this->productRepository->save($product); // This is important - the version provided and the version returned will be different objects
        
        //STOCK
        $stockItem = $this->stockRegistry->getStockItemBySku($product->getSku());
        $stockItem->setIsInStock(1);
        $stockItem->setQty(0);
        $this->stockRegistry->updateStockItemBySku($product->getSku(), $stockItem);
        return $product->getId();

Please help me out.
