Svelte, redirect index.html page question

Hi guys, I got stuck on simple redirect. So, in root, I have index.html page (simple page, without F7 and svelte) and test.html (which is working index.html with f7) so when user click on ‘redirect’ link it should be redirected to ‘real, working f7 svelte’ in my case test.html.

But I got page not found, any help/hint appreciated. Thank you in advance!
