when trying to add a new shipping method and Fedex is installed i get a 500 error & this message in the drupal logs:
TypeError: Argument 2 passed to Drupal\Component\Plugin\PluginManagerBase::createInstance() must be of the type array, null given, called in .../modules/contrib/commerce/src/Plugin/Field/FieldType/PluginItem.php on line 131
looks like the issue is that FedExPluginManager does not createInstance method, and therefore uses
PluginManagerBase::createInstance() which requires a $configuration array that is not being defined.
