The download destination only works when accessed through a http client.

I've the following error:

The download destination only works when accessed through a http client.

when I'm trying to download db backup via Chrome using freshly installed module on clean installation of Drupal.

Code:

  public function checkWritable() {
    // Check that we're running as a web process via a browser.
    // @TODO: we could check if the 'HTTP_ACCEPT' header contains the right mime but that is probably overkill.
    if (!isset($_SERVER['SERVER_ADDR'])) {
      throw new DestinationNotWritableException(
        "The download destination only works when accessed through a http client."
      );
    }
  }

Probably, because I'm using PHP builtin server via: php -S localhost:8888, so my SERVER_ADDR isn't defined, but SERVER_NAME is.

$_SERVER["SERVER_NAME"] = localhost
