Hi @gabriel_helle 

There might be some issue with the deployment. You can regenerate generated folder using compile command.

Try the following command once:

find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \; && chmod u+x bin/magento

You can use sudo as well.

Then try following commands once n sequence to re generations.

chmod -R 0777 var/ pub/ generated/
rm -rf var/cache/* var/view_preprocessed/* generated/* pub/static/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

If still you got the same error then run

composer update

and run the above commands again in sequence.

I hope it will help you!
