Magento Upgrade (2.4.3-p1 >> 2.4.4) Compilation Error

Question

I am upgrading our current site from 2.4.3-p1 to 2.4.4. I had to apply multiple patches for upgrading. However, while running di:compile, its give me error as below

MiBInterface "Magento\GraphQl\Helper\Error\ExceptionMessageFormatterInterface" not found#0 /var/www/magento/vendor/composer/ClassLoader.php(571): include()

#14 /var/www/magento/bin/magento(23): Symfony\Component\Console\Application->run()
#15 {main}

When I check the module mentioned in error ie: Magento\GraphQl\Helper, I see it has been removed from 2.4.4 and in my composer.json, the module is already under replace.

However, couple of classes still uses it. If I remove this entry, other error comes. I am unsure how to overcome/resolve this.

Any suggestion will be appreciated.

Magento\GraphQl\Helper\Error\ExceptionMessageFormatterInterface seems to be new in Magento 2.4.4. It is used by the module itself, but also by other GraphQL modules (search for "implements ExceptionMessageFormatterInterface").

If I understand your question correctly, then you have disabled the module in the composer.json using a replace property to replace it with * (like is done in the yireo/magento2-replace-graphql module module). I would suggest to remove this (and probably other) replace entries and properly install the module using Composer to get back the behaviour as intended by Magento.

BTW I have used the Composer replace trick in the past, but stopped using it, as it introduced to many errors. If I really want to disable a module, I do this via app/etc/config.php.
