Magento 2 - Uncaught Error: Class "DOMDocument"

Question

I am using magento commerce cloud, and when I try to execute selected command below:

vendor/bin/mftf generate:tests

Then this error is shown in console:

Uncaught Error: Class "DOMDocument" not found in ../vendor/magento/magento2-functional-testing-framework/src/Magento/FunctionalTestingFramework/Config/Dom.php:366

All solutions online are pointing to the same thing, php extensions dom and xml are missing. I installed both of them through DockerFile in config/php folder and when I checked enabled php extensions with php -i. Both are installed.

But error still happens again. Thanks!

Answer 1

I would suggest creating a php file with phpinfo() and check both extensions there + running the composer update once you are sure the extensions are present.
