DevTools failed to parse SourceMap after rewrite index.php

So I have updated to Nextcloud 12

Many things broke, like a lot… such a painful migration from 11 => 12. Themes are working totally differently now, but nvm that, all is working Okay now except:

Once I edit config and add 'htaccess.RewriteBase' => '/', I start getting the error below:

DevTools failed to parse SourceMap:

Help please

I’m getting this with v13. How did you end up fixing it?

I ended up not using rewrite
