I just ran into this issue myself. To reproduce it, install Xdebug 3 on PHP 7.3 or 7.4 with Magento 2.4 and MFTF 3.1.1 and run any bin/magento command. It's also breaking PHPCS in PhpStorm.

Seems to be related to new xdebug v3.0.0

For the moment, I did a quick composer remove magento/magento2-functional-testing-framework and that seems to make my dev environment work again. But this is surely a temporary fix...

Any way to downgrade Xdebug?

[Yonn-Trimoreau]

pecl install -f xdebug-2.9.8

[lfluvisotto]

vendor/magento/magento2-functional-testing-framework/src/Magento/FunctionalTestingFramework/_bootstrap.php

Replace:

if (!(bool)$debugMode && extension_loaded('xdebug')) {
    xdebug_disable();
}

By:

if (!(bool)$debugMode && extension_loaded('xdebug')) {
    if (function_exists('xdebug_disable')) {
        xdebug_disable();
    }
}

I faced the same issue after updating and upgrading my Ubuntu server. I needed to downgrade xDebug version to fix this issue for Magento 2.4.1 and PHP7.4:

sudo pecl install -f xdebug-2.9.8

If you get “phpize: command not found” error, you can run pecl command again:

sudo apt-get install php7.4-dev

I use multiple PHP versions on my server. For older version like PHP7.3, you modified its php.ini file and add the path of xdebug-2.9.8. On ubuntu, I edited php.ini by running:

sudo vi /etc/php/7.3/fpm/conf.d/20-xdebug.ini

and added:

zend_extension=/usr/lib/php/20190902/xdebug.so

@wasimhc I have the same issue. We downgraded our xdebug aswel to 2.9. It would be awesome if this can be resolved. Since it now adds a lot of errors to my console. Can this ticket be reopened.

[wasimhc]

@leonhelmus How are you sure xDebug has been downgraded to 2.9.8 or 2.9 at your end?
