s3fs, cdn, advagg integration

On a fresh install of Drupal using drupal:8.6-apache Docker image, I observed the following behavior:

• When s3fs is installed and configured with the following:
  

  /**
   * s3fs related config
   */
  $settings['s3fs.access_key'] = 'S3_ACCESS_KEY';
  $settings['s3fs.secret_key'] = 'S3_SECRET_KEY';
  $config['s3fs.settings']['root_folder'] = 'www-root';
  $config['s3fs.settings']['bucket'] = 'my-unique-bucket';
  $config['s3fs.settings']['use_cname'] = TRUE;
  $config['s3fs.settings']['domain'] = 'example.cloudfront.net';
  $config['s3fs.settings']['use_https'] = TRUE;
  $config['s3fs.settings']['no_rewrite_cssjs'] = TRUE;
  $settings['s3fs.use_s3_for_public'] = TRUE;
  $settings['s3fs.use_s3_for_private'] = TRUE;
  

• When cdn module is enabled
• When advagg is enabled

I get the following error:

When the config $settings['s3fs.use_s3_for_public'] is set to FALSE or not configured or either of advagg and cdn modules are uninstalled, the error is gone.

I needed s3fs, cdn and advagg for my particular use case so I hacked away s3fs' module by the attached patch.
I am not a Drupal developer. I am a SysAdmin with a little bit of PHP knowledge.

Anyone encountered this issue?
