Debugging information follows.

StatusText: OK
ResponseText: Drupal\Core\Config\PreExistingConfigException: Configuration objects (ds_extras.settings) provided by ds_extras already exist in active configuration in Drupal\Core\Config\PreExistingConfigException::create() (line 65 of /var/www/html/test/varbase8c1t1/docroot/core/lib/Drupal/Core/Config/PreExistingConfigException.php).

The batch function will be called in the very late in the batch queue ..
and the code for importing configs will run first.
Then when a module is installed, it will find the config in the active config.
But also .. some other modules will not find some modules and configs will not be installed

To fix .. all should be changed to batch and put into the batch queue
I will revert the code
.. and only keep

foreach ($module_info_data['install'] as $module) {
  if (!\Drupal::moduleHandler()->moduleExists($module)) {
   \Drupal::service('module_installer')->install([$module], TRUE);
  }
}

instead of

\Drupal::service('module_installer')->install($module_info_data['install'], TRUE);
