Spring Boot - change serviceUrl paramether

Hi,
My app is running in subcontext path (like www.myapp.com/apps/settings). It is standard Vaadin + Spring Boot app. The problem is vaadinServlet which is always map to www.myapp.com/vaadinServlet. The solution would be the change of serviceUrl paramether from “/vaadinServlet” to “./vaadinServlet”. Any idea how could i set this paramether?
Thank you,
Regards

Hi,
I found solution by adding sub_filter in nginx config. For example :

      location /apps/settings/ {
                    client_max_body_size    50M;
                    proxy_read_timeout 600;
                    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header  X-Real-IP  $remote_addr;
                    proxy_set_header Host $http_host;
                    proxy_redirect off;

                    proxy_pass http://127.0.0.1:8087/;
                    #proxy_redirect  http://127.0.0.1:8087/ http://127.0.0.1/;
                    
					sub_filter_once off;
                    sub_filter_types text/html;
                    sub_filter "/vaadinServlet" "./vaadinServlet";
     }
