Problems while tryin' to setup a new instance

Dear folks,

just tried to setup a new instance (https://git.fitko.de/-/ide/project/fitko/architekturmanagement-standards/koordination-it-standards/standardisierungsagenda/standardisierungsagenda-doku) based on the docusaurus-template - and came across a few probs. Hope you can help!

1st issue:

[ERROR] Error: Docusaurus found broken links!  
Please check the pages of your site in the list below, and make sure you don't reference any path that does not exist.  
Note: it's possible to ignore broken links with the 'onBrokenLinks' Docusaurus configuration, and let the build pass.   
Exhaustive list of all broken links found:  
- On source page path = /standardisierungsagenda/jvo-draft/glossary:  
     -> linking to /standardisierungsagenda/jvo-draft/docs/terms/unicorn

After setting 'onBrokenLinks' to warn (instead of throw), I came across the
