This is working code, as a workaround in using entityquery:

look in theme.liquid to add the javascript to the head
look in header.liquid to find the header HTML in the theme.

Put this in their config:

{
  "send_stats": false,
  "translate_images": false,
  "language_selector" : [
            {
                "U" : "U",
                "T" : "T",
                "I" : "OneLinkJS_langSel",
                "C" : "C",
                "position" : "first"
            }
        ]
}

and the one liner in the head of the document.

 \Drupal::logger('ipc_order_sync')->notice('Adding the following order to the enqueJob @order_id
         with transaction id of @transaction_id',
          [
            '@order_id' => $order['order_id'],
            '@transaction_id' => $order['transaction_id'],
          ]);

In your settings.php:

$settings['foo'] = 'bar';

In your code:

use Drupal\Core\Site\Settings;

Settings::get('foo', 'mydefaultvalue');

 drupal advancedqueue:queue:process ipc_transaction_sync 

or

 drush advancedqueue:queue:process ipc_transaction_sync

or

 drush advancedqueue:queue:process ipc_order_sync

If there are not dependencies and it's not a pain to mock in a unit test, or for re-use then static is fine. A service lets you encapsulate everything and all the dependencies using dependency injection, to make sure all the dependencies are easy to setup.

Temporary fix for:
The URI '' is invalid. You
must use a valid URI scheme. in
Drupal\Core\Url::fromUri() (line 290 of
/Users/jamesbarnett/sites/IPC/ipcedtr/

This is how I get around that issue locally….
docroot/core/lib/Drupal/Core/Url.php
Line:290
return static::fromUri('http://localhost');

These directions worked with some modifications: https://javorszky.co.uk/2018/05/03/getting-xdebug-working-on-php-7-2-an…

I was using PHP on the command line with homebrew, so installed xdebug with pecl install xdebug
then I was able to put the following in the php.ini file, find the php.ini file for the command line by running php --ini and look for Loaded Configuration File in the output.

The below is for XDEUG 3.0

      $result = \Drupal::entityQuery('group')
        ->condition('type', $type)
        ->range(0, 20000)
        ->accessCheck(FALSE)
        ->execute();

make sure to set accessCheck to FALSE or you'll get no results, entityQuery respects permissions and the drush user won't be running as any particular user.
