PageBuilder Internal Server Error when adding Products

[memen45]

After some testing I found a weird bug with the PageBuilder when this module is enabled.

Steps to reproduce

• install the package using composer. Then run the usual upgrade and compile commands.

  composer require "web200/magento-seo"
  bin/magento setup:upgrade && bin/magento setup:di:compile && bin/magento indexer:reindex && bin/magento cache:flush
  sudo chgrp -H -R www-data var pub/media pub/static generated

• now open the admin > content > pages and select a page and choose Edit.

• if it does not already have it, add a "Add content" > "Products" block to the pagebuilder and click settings of the Products block, then Save the block.

• if it already has the Products:

• observe the following error: "A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later."

• Observe in the browser console a failed request:

  XHRPOST
  http://ubuntu-container.lxd/admin_/pagebuilder/stage/preview/key/bf8605a97faf8b3f048d3e070f21f911d636cc428e95a71f6fd4c3bc7469c18f/?isAjax=true
  [HTTP/1.1 500 Internal Server Error 146ms]

• after removing and upgrading magento again, the error disappears and everything works fine

  composer remove "web200/magento-seo"
  bin/magento setup:upgrade && bin/magento setup:di:compile && bin/magento indexer:reindex && bin/magento cache:flush
  sudo chgrp -H -R www-data var pub/media pub/static generated

  Logs

  Nothing to be found in the exception/system/debug logs that is related to this.

Any idea where the error could be coming from or where to look?

Still present in Magento 2.4.7-p2

Would be happy to help, but I am not sure what would help you reproduce and find the cause of the bug!

System Info:

• Ubuntu 24.04.1 LTS
• Magento 2.4.7-p2
• PHP 8.1
• Mariadb 10.11.8

This is a development system, not in production mode.

Adding a di.xml file to the adminhtml directory with the following contents seem to have solved the issue:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Web200\Seo\Api\CmsPageUrlRetrieverInterface" type="Web200\Seo\Service\HrefLang\CmsPageUrlRetriever" />
    <preference for="Web200\Seo\Api\CategoryUrlRetrieverInterface" type="Web200\Seo\Service\HrefLang\CategoryUrlRetriever" />
    <preference for="Web200\Seo\Api\ProductUrlRetrieverInterface" type="Web200\Seo\Service\HrefLang\ProductUrlRetriever" />
</config>

Should there be more used from the frontend/di.xml file?

Also, are you open to receive and merge pull requests?
