Drupal 8.x

I note that with Drupal 8 it's highly recommended to use Composer to manage sites. So...

Installing Drupal using the instructions from https://www.drupal.org/docs/develop/using-composer/using-composer-to-install-drupal-and-manage-dependencies using drupal/reccomended-project.

1. Run composer create-project drupal/recommended-project [my_site_name_dir]

I have a pile of sites successfully running Drupal 8.8.2 and although they all use the directory structure with core, modules, themes etc. in web directory so vendor directory, composer.json, composer.lock and a few others can sit outside of root, none of them use anything "recommended". If using composer to install 8.8.x works using a recommended approach then trying to subsequently get composer to install drupal console or drupal_commerce fails and reports "Killed" which is a usually a sign of memory shortfall.

I am trying to get a D8 with drupal commerce site ready top open it to the public.

It is currently open to testers.

The site is an upgrade from D7 with ubercart. I have tried to run upgrades after the one I now use but those upgrades did not import orders which I do need to have as a reference.

I have had an wsod before which I was able to solve by comparing the view settings of an empty install with mine and I had changed stuff I should not have changed.

However, for this error it dous not work.

Here is the error report:

Hi,

I installed modul Quiz 8.x-5.x-dev.
Drupal 8.8.2.

When I creat quiz question type, I keep getting error message:
"The website encountered an unexpected error. Please try again later."

Drupal\Core\Entity\EntityMalformedException: The entity does not have an ID. in Drupal\Core\Config\Entity\ConfigEntityStorage->save() (line 252 of core/lib/Drupal/Core/Config/Entity/ConfigEntityStorage.php).

Can you help me resolve this error message please?

Many thanks,
