Error updating 2.4.3-p1 to 2.4.4

[Agustín Farías]

I'm trying to upgrade a cloud sandbox project to 2.4.4. I changed the cloud metapackage depdendency in composer.json from:

"magento/magento-cloud-metapackage": ">=2.4.3 <2.4.4"

to 

"magento/magento-cloud-metapackage": ">=2.4.4 <2.4.5"

And changed the PHP dependency to 8.1 in .magento.app.yaml. After pushing the changes I get this error on the deployment log (in either integration branches or master):

 W: > php ./vendor/bin/ece-tools schema:generate || true
    W: PHP Fatal error:  During inheritance of Countable: Uncaught RuntimeException: Deprecated Functionality: Return type of Composer\Repository\ArrayRepository::count() should either be compatible with Countable::count(): int, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /app/vendor/composer/composer/src/Composer/Repository/ArrayRepository.php on line 286 in /app/vendor/magento/ece-tools/src/App/ErrorHandler.php:68

It seems to be related to the Composer dependency in the vendor folder, but I can't figure out how to tell Magento to use a more recent one. Not sure if this is the exact error. Any suggestion will be more than welcome.

Hi Agustin,

I have been having a similar issue, did you manage to resolve it?

Thanks

Have the same issue with php 8.1. Any solutions or suggestions how to fix it?

I found that we also need to update composer root update plugin. Maybe it helps to somebody 

composer require magento/composer-root-update-plugin ~2.0 --no-update

I fixed this by updating symfony/console. The original requirement in my composer.json was 4.4.26. I changed it to ~4.4.0 and ran composer update so it would install the latest version of 4.4.x. In my case, I ended up with 4.4.44 and I no longer see the PHP error.

You can use the following url to read more about the composer-root-update-plugin.

https://github.com/magento/composer-root-update-plugin/tree/develop/src/Magento/ComposerRootUpdatePl...

When upgrading to a new version, first run below command. This makes sure that your root composer.json dependencies are updated to reflect the new magento version. After that run `composer update` to upgrade magento to the new version.

composer require-commerce magento/product-community-edition 2.4.4 --no-update --verbose
