Code

function _drupal_get_error_level() {

  // Raise the error level to maximum for the installer, so users are able to
  // file proper bug reports for installer errors. The returned value is
  // different to the one below, because the installer actually has a
  // 'config.factory' service, which reads the default 'error_level' value from
  // System module's default configuration and the default value is not verbose.
  // @see error_displayable()
  if (InstallerKernel::installationAttempted()) {
    return ERROR_REPORTING_DISPLAY_VERBOSE;
  }
  $error_level = NULL;

  // Try to get the error level configuration from database. If this fails,
  // for example if the database connection is not there, try to read it from
  // settings.php.
  try {
    $error_level = \Drupal::config('system.logging')
      ->get('error_level');
  } catch (\Exception $e) {
    $error_level = $GLOBALS['config']['system.logging']['error_level'] ?? ERROR_REPORTING_HIDE;
  }

  // If there is no container or if it has no config.factory service, we are
  // possibly in an edge-case error situation while trying to serve a regular
  // request on a public site, so use the non-verbose default value.
  return $error_level ?: ERROR_REPORTING_DISPLAY_ALL;
