Why is this happening and how could I fix it.

any ideas?

Drupal redirects to /core/install.php when I try to open page including a SQLite query

I have a Drupal site on a web server. On one page of the site, I want to print out information from a sqlite database. But if I enter the url to the page, I get redirected to /core/install.php

I integrated the database into the /sites/defualt/settings.php with the following code:

$databases['external']['default'] = [
'driver' => 'sqlite',
'database' => '/gesamtausgabe_2019.sqlite',
];
