Hi @Volodymyr

Try this one -

foreach ($results as $result) {
$categoriesForProduct = $this->findOrFail($result->id)->categories;
}

and Make sure that -

$this->findOrFail($result->id);

returns a product Model.

Thanks

Hi @rahul.

You are right about object verification.
$categoriesForProduct = $productRepository->find($product->id);
if ($categoriesForProduct) {
foreach ($categoriesForProduct->categories()->get() as $categoryProduct ) {
