Magento2: Class Magento\Catalog\Model\Product\Attribute\Backend\Media does not exist

[ashvinimarwal]

On Product Save
Class Magento\Catalog\Model\Product\Attribute\Backend\Media does not exist
/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 93
Any idea ?

From quick search https://github.com/magento/magento2/issues/2790#issuecomment-220233773 may help. Looks like Magento code and sample data versions are not in sync on your instance.

Class Magento\Catalog\Model\Product\Attribute\Backend\Media does not exist
/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php
Kindly see the screenshot.

[misha-kotov]

How did you perform the data migration? Did you use our data migration tool by any chance?

[ashvinimarwal]

i used this Tool and i have completed migration without any error.

Did you do http://devdocs.magento.com/guides/v2.1/comp-mgr/cli/cli-upgrade.html#upgrade-cli-upgr also? (the most important part is php bin/magento setup:upgrade).

[ashvinimarwal]

Hi @orlangur ,
I also tried this but still facing the same issue.
now it's showing on frontend

Hi,
The class Backend/Media was removed in core. You can see diff in this commit https://github.com/magento/magento2/commit/0f0063045b50e1dafa260b97a1a00bf9fa92e74b#diff-7efc962fb113e767187c2ce8d5017415
But the eav attribute backend model class still in your database.

• You can do the fix by run this SQL Query

UPDATE eav_attribute SET backend_model = NULL, backend_type = 'static' WHERE attribute_code = 'media_gallery'

Make sure you have backup your database on safe place before you run this query.

Thank you @victor-v-rad

Did you update the new source code for your magento. I see the FileInfo class exist here (version 2.2) https://github.com/magento/magento2/blob/2.2/app/code/Magento/Catalog/Model/Category/FileInfo.php . Please check and make sure you have this file

[syed786hasan]

No I am still using 2.1.7 and problem persists here
