Editor throws error when wordpress is installed in a subdirectory and permalinks are activated

[iamklaus]

I have wordpress installed in a subdirectory. As soon as I activate permalinks in the wordpress settings, I cannot edit pages anymore. I see a blank page and errors in the console. Everything else works. I can even edit blog posts without any problems. It only occurs editing pages. Here is my url:

​https://dachfensterinfo.de/cms/

I use nginx. Here is my config:

upstream wordpress-prod-php-handler {
    server unix:/var/run/php/php8.2-fpm.sock;
}

server {

    server_name dachfensterinfo.de;
    root /var/www/dachfensterinfo.de.django/;

    location /cms {
    
        alias /var/www/dachfensterinfo.de.wordpress/;
    	index index.php;
    	try_files $uri $uri/ /cms/index.php;
