TYPO3 Core

If you don't have any language with base: / configured, the static route of robots.txt is no reachable.

In the example below I have two languages configured. Every language is prefixed with two letter country code. So http://intro.ddev.local/ is redirected to http://intro.ddev.local/en/ as it is the default language. Exectly the behavior I like to have for all pages.

Now there is the robots.txt in routes which doesn't have any language prefix (as it needs to be in the docroot). If I try to open http://intro.ddev.local/robots.txt i get redirected to http://intro.ddev.local/en/. And http://intro.ddev.local/en/robots.txt throws an page not found error.
I added two other Text routes which are prefixed with language codes and they are reachable: http://intro.ddev.local/en/mytext.txt http://intro.ddev.local/de/meintext.txt
