2.4.4 not compatible with php 8.1?

[rbrown]

Sorry, I can't see anywhere mentioning whether this is compatible with 8.1, but after upgrading form 2.4.3, running bin/magento returns

bin/magento setup:upgrade
PHP Fatal error:  During inheritance of Iterator: Uncaught Exception: Deprecated Functionality: Return type of Migration\ResourceModel\AbstractCollection::current() should either be compatible with Iterator::current(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /magento2/vendor/magento/data-migration-tool/src/Migration/ResourceModel/AbstractCollection.php on line 35 in /magento2/vendor/magento/framework/App/ErrorHandler.php:61

I don't think it's a caching error, https://github.com/magento/data-migration-tool/blob/2.4-develop/src/Migration/ResourceModel/AbstractCollection.php is not specifying the return type?

It seems like the data-migration-tool should use attributes for places
like in the magento2 repository

@rbrown the issue fixed in 2.4-develop Please install DMT from that branch or use php 7.4 as a workaround while migration

Hi, what is the status here? When will a fix be ready for Adobe Commerce 2.4.4?

[vrielsa]

Had the same issue for our client. We applied the PHP 8.1 fixes commit as a patch until it gets released.
