Troubleshooting

This section covers common troubleshooting scenarios when migrating a Drupal site from another host to Pantheon's platform.

Provided host name not valid

If you receive the error message "The provided host name is not valid for this server.", then update your settings.php file with a trusted host setting. Refer to the Trusted Host Setting documentation for more information.

Site-local Drush Is Required for Drupal Sites

Do not remove drush/drush from composer.json. If it is removed, terminus drush commands will fail with errors related to Twig.

Pantheon Launch Check Status Error: services.yml does not exist

After you set up Drupal, the following error might be displayed in the Best practices section of the Pantheon Launch Check:

x sites/default/services.yml: services.yml does not exist! Copy the default.service.yml to services.yml and refer to https://www.drupal.org/documentation/install/settings-file for details.

Create services.yml file inside sites/default directory by copying default/services.yml file. Refer to https://www.drupal.org/documentation/install/settings-file for details.

Ensure your site's Development Mode is set to Git. Use the terminal on the local machine where you cloned the site, and from the project's root directory:

1. Copy default.services.yml to services.yml:

   cp web/sites/default/default.services.yml web/sites/default/services.yml

2. Commit and push:

   git add web/sites/default/services.yml && git commit -m "init services.yml"
   git push origin master
