Magento 2 : Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails while saving a duplicate category

Question

I have installed Duplicate categories Extension in the client site(Magento 2.3.2), while duplicating categories I'm facing this error,

{"0":"SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (my_db.catalog_url_rewrite_product_category, CONSTRAINT CAT_URL_REWRITE_PRD_CTGR_PRD_ID_CAT_PRD_ENTT_ENTT_ID FOREIGN KEY (product_id) REFERENCES catalog_product_entity (entity_), query was: INSERT INTO catalog_url_rewrite_product_category (url_rewrite_id,category_id,product_id`) VALUES (?, ?, ?),

EDIT

Error is showing at this line in $copy->save()

$copy = $this->categoryFactory->create();

$copy->setIsActive(true);
$copy->setName($category->getName());
$copy->setParentId($parentCategory->getId());   
$copy->setPath($parentCategory->getPath());
$copy->setData('description',$sub_description);
$copy->setData('meta_description',$sub_meta_description);
$copy->setData('meta_keywords',$sub_meta_keywords);    

$newUrl = $this->getNewUrl($category, $parentCategory,$count);
$copy->setUrlKey($newUrl);

if($copy_products == 1){   

    $copy->setPostedProducts($category->getProductsPosition());
}
$copy->save();

I have also tried saving with store id and repository it doesn't work for the category that I want to duplicate, code is working for other categories. I think there is a non-existential category id or product id i don't understand how do I find that in the database.

Client has done Migration on the site before installing the module.

Does anyone has any idea? why this error is showing and how do I resolve it.

Answer 1

Finally, I resolved this issue with the help of this Reference link

Ran below query to find and delete duplicates,

Delete from url_rewrite where entity_type='product' and entity_id NOT IN (Select entity_id from catalog_product_entity);

After deleting I ran upgrade-deploy and indexer commands and it's working for me.

Hope it Helps.
