Configuración de NGINX para múltiples instalaciones de Symfony usando subcarpetas

Question

Tengo una instalación de Shopware (versión 6.5.5.1) ejecutándose en mi dominio. Quiero agregar más instalaciones independientes de Shopware, usando el mismo dominio (para diferentes idiomas/países).

Por ejemplo, midominio.com y midominio.com/de, midominio.com/en, etc.

Tengo dos instalaciones independientes:

1. /var/www/html/developer/dev-test(gerwin-gesundheitsprodukte.com)

2. /var/www/html/developer/dev-app1(gerwin-gesundheitsprodukte.com/app1)

La primera instalación (gerwin-gesundheitsprodukte.com) funciona bien, incluido el backend.

Para la segunda instalación de Shopware, intenté ampliar mi configuración de NGINX utilizando un proxy inverso (proxy_pass 127.0.0.1:81).

También se abre el escaparate de la segunda instalación (gerwin-gesundheitsprodukte.com/app1), pero una vez que quiero acceder al backend (gerwin-gesundheitsprodukte.com/app1/admin), aparece un error:

Shopware\Administration\Controller\AdministrationController::index(): Argument #2 ($context) must be of type Shopware\Core\Framework\Context, null given, called in /var/www/html/developer/dev-app1/vendor/symfony/http-kernel/HttpKernel.php on line 182

¿Parece que alguna información ( $context) no pasa el proxy?

¿Qué hay de malo en mi archivo de configuración? ¿Es generalmente correcto el enfoque de usar proxy_pass para esto?

Parte relacionada de mi configuración:

server {

    index index.php index.html;
    server_name gerwin-gesundheitsprodukte.com;

    client_max_body_size 128M;

    location ^~ /app1 {
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_pass http://127.0.0.1:81;
        proxy_redirect off;
    }
#rest is Shopware standard config for first installation
}

server {
#the server block for the second installation
    listen 81;
    server_name 127.0.0.1;

    set $subdir_root /var/www/html/developer/dev-app1/public;
    root $subdir_root;

    rewrite ^/app1(.*)$ /$1 break;
    sub_filter "https://gerwin-gesundheitsprodukte.com/" "https://gerwin-gesundheitsprodukte.com/app1/";
    sub_filter_once off;

#rest of the config
}

Aquí está la configuración completa:

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_pass http://127.0.0.1:81;
        proxy_redirect off;
    }
