How can I fix the deprecated functions with M 2.4.4 and PHP 8.1

[krasho]

I am updating a project from M 2.4.0 to M 2.4.4 and I have seen some deprecated errors when I use PHP 8.1

for example this:
Deprecated Functionality: Zend_Http_UserAgent implements the Serializable interface, which is deprecated.

The file is:
vendor/magento/zendframework1/library/Zend/Http/UserAgent.php

Class Zend_Http_UserAgent implements Serializable
{
}

how can I fix this without changing the vendor file? I already saw messages to explode and strpos functions

thanks

For not best practices...

Edit app/boostrap.php to add error_reporting(E_ALL ^ E_DEPRECATED);

I found this package in the composer.json file
"magento/magento2-functional-testing-framework": "^3.7",

this package is adding the zendframework1 package.

is it possible to remove that?

thanks

If you test ok, it will be fine.

You may use compose remove "spec module" to remove, it will help you check the dependency.

no, this didn't work. I am trying your first recommendation.

but I have the same question, why is few people talking about this? doesn't this happen in a clean installation?

thanks
