Image migration fails

[matthewboman]

Following your article I updated the repository with my sites URL and ran into the following error running migrations:

In MigrateToolsCommands.php line 268:

[Exception] You must specify --all, --group, --tag or one or more migration names separated by commas

Drupal 8.6.3 Drush 9.4

If I try migrating only articles it works, but then images are not migrated.
