We are trying to achieve SEO for our mendix applications and the way that search engines getting the content of the page is to allow crawlers to decipher the source code from it to be reached later, However, the issue is that whenever you try to open a source code for the page only you will see a javascript tags, therefore, crawlers will not be able to see the content also we tried to use https://prerender.io but our applications are on cloud using nignx web server and we cannot access web server files.
