Error to display category containing product bundle

[ydessert]

We recently updated our CE from 2.4.2 to 2.4.3p1 and face a problem with the frontend display of product categories containing product bundle. We don't have error if the category do not include any product bundle.

We have tested with provided Luma theme and we have the error.

The error reported is :

main.CRITICAL: Error: Call to undefined method Magento\Catalog\Model\ResourceModel\Product\Flat::getLinkField() in /var/www/html/magento2/vendor/magento/module-eav/Model/Entity/Collection/AbstractCollection.php:1066

I saw that there was a lot of modifications on product bundles in 2.4.3, maybe there is a explanation around that.

Any similar experience to fix that ?

Best regards,

Yannick

For other folks getting the same issue, it seems that it's already reported for 2.4.3 under issues #33935 .

This is bug is linked to Flat catalog.

Disabling Flat Catalog Categories and Products solved the issue.

Hope it helps.
