Product Alert emails are not translated

[dandrikop]

I have Magento 2.4.6-p1 running on PHP 8.1.20 and the email messages associated with Product Alerts are not translated. I have a multilingual store with 7 locales and I have successfully translated every text related with both Magento core modules and 3rd party modules except from Product Alert messages. I have verified that the appropriate texts are found in the i18n/CSV files.

This must be a bug of Magento and not some problem related with my own Magento installation.

It seems that the problem with translating the emails associated with product alerts has been identified for Magento 2.4.7:

https://github.com/magento/magento2/tree/2.4.7-beta1/app/code/Magento/ProductAlert

At the updated Product Alert module, I noticed that only the file app/code/Magento/ProductAlert/Model /Mailing/AlertProcessor.php has changed. I tried the updated Product Alert module, but unfortunately the problem with translations persisted. Of course, Magento 2.4.7 is still in beta phase, so maybe the problem is fixed till version 2.4.7 becomes stable.

Anyway, based on directions below:

https://github.com/magento/magento2/issues/35674

I created and applied the below patch and tested it on Magento 2.4.6-p1 running PHP 8.1.20, and it worked without any errors recorded in the log files:
