Magento 2 admin error: Product does not exists

After migrating Magento to version I am facing below issues while navigating to Product page.

Error: Class Magento\Catalog\Model\Product\Attribute\Backend\LayoutUpdate does not exist

Also I am going to editing product in admin panel getting the below error

Error: Product does not exists

Product does not exists

In Magento 2 some version Magento created the LayoutUpdate file with the attributes custom_layout_update_file, When we revert back version, the attribute calling the file and cause the issue.

Solution:

Go to your Database and search in table eav_attribute table like below sql. If you will find two records and just remove them.

Find or Select query:

Delete query:

After delete two records from database run following command via cli

If you have redis, you will need to flush the cache from it.

redis-cli flushdb – Delete all the keys of the currently selected DB.
redis-cli flushall – Delete all the keys of all the existing databases, not just the currently selected one.
