Sorry for bad english, so i'll try formally

1. go to views, create new view consist articles without page and block
2. add feed, format is RSS Feed, show Fields
3. add fields:

Content: Title
Content: Body
Content: Authored by
Content: Authored on
Content: Path

4. assign fields at show settings, title to title, body to description, path to link, etc
5. add path at feed settings, for ex. /test.xml
6. save view

try to open example.com/test.xml show error, something about "Error, try later"

Reports record:

InvalidArgumentException: The URI 'base:19' is invalid. You must use a valid URI scheme. в Drupal\Core\Url::fromUri() (string 301 at file /home/hooligan.site/web/hooligan.site/public_html/core/lib/Drupal/Core/Url.php).

where 19 - last Nid

If delete [Content: Path] from fields list of feed than all ok, but xml-node
is empty naturally

Clear installation have no this problem, but i want fix it in production.

Thanks in advance for your help
