Hi, I hava a problem with the sites.conf file. I tried adding following line:

Drupal 8 C=composer create-project drupal-composer/drupal-project:8.x-dev %s --stability dev --no-interaction

When I try quick creating this project I get the following error:


As you can see after the create-project part drupal-composer is somehow replaced with drupal- leading to the error.

Anyone an idea why this is happening?

Thanks in advance!
