Magento\Catalog\Model\Category\Attribute\Backend\DefaultSortby" does not exist in Magento 2.4.7-p2

[mahade hassan_khan]

I'm facing an issue while trying to create a category in Magento 2.4.7-p2  The following error appears when i click categories from Catalog from the Magento 2 Admin

1 exception(s):
Exception #0 (ReflectionException): Class "Magento\Catalog\Model\Category\Attribute\Backend\DefaultSortby" does not exist

What I've tried so far:

1. Ran php bin/magento setup:di:compile, php bin/magento setup:upgrade, and php bin/magento cache:flush.
2. Checked the file path vendor/magento/module-catalog/Model/Category/Attribute/Backend/DefaultSortby.php, and it seems that the file doesn't exist.
3. Reinstalled the magento/module-catalog using composer remove and composer require.
4. Disabled third-party modules to check for any extension conflicts.
5. Verified file permissions and recompiled static content.
6. Enabled developer mode and checked logs in var/log/exception.log and var/log/system.log.

Despite trying these steps, the issue persists. Has anyone encountered a similar issue or knows what might be causing this? Any help or guidance would be greatly appreciated!

Hello @mahade hassan_khan,

1. Disable all third party module once.

2. run all commands and check.

3. if issue still persists, then check any attribute using that class in database.

4. Check eav_attribute table backend class in database.

Let me know if you find anything in database table.

I hope it helps!

It looks like you're missing the DefaultSortby class in Magento 2.4.7-p2. Here’s what you can try:

1. Confirm Version: Make sure your Magento version is 2.4.7-p2.
2. Check Documentation: Verify if the class was deprecated or removed in this version.
3. Review Custom Code: Ensure no custom modules are referencing the missing class.
4. Update Modules: Ensure all third-party modules are compatible and updated.
5. Database Check: Run php bin/magento setup:db-data:upgrade to sync the database schema.
6. Consult Resources: Look for similar issues on Magento forums or GitHub.
