❌ https://process-analytics-process-analytics-dev-site_preview-pr-1179.surge.sh/model-generation-application-conditions returns a 404 HTTP code, displays the 404 error page, then a blank page. The final URL in the browser is https://process-analytics-process-analytics-dev-site_preview-pr-1179.surge.sh/
Tested on Ubuntu 20.04 with Chrome 117.0.5938.149 and Firefox 118.0.1

We don't want to return a HTTP 404, but a 200 or 301.

I suggest to redirect to the model-generation application, if possible by first returning a 301 and the target page, or if not, internally displays the target page and returns HTTP 200

⚠️ The redirect works, but when it first loads, it displays a blank page.
When you refresh it or try to go to the old page again, the new page is displayed.

I've tried redirecting to the /model-generation-application page instead of the home page, but I get the same problem.

I suggest keeping the default redirect page: /404.
There's a link to go back to home or select the page the user is interested in.
