If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

We use SSR with a cms and have a catch-all route ([...path].astro), ask our cms to get the page and render it. If the path is not available, the cms returns a "page not found" component which we display AND return a 404 status code. That works fine on the server but on development we always see the astro 404 overlay (I'm aware of the custom 404, but this is not how we work).

What's the expected result?

The 404 astro overlay should not be displayed in development - our 404 should be displayed.

That works fine on the server

Can you please update your reproduction with a valid adapter? (node, I suppose)

Hey there! I've checked out the stackblitz and have a small question.

the normal code gets the content to display back from a cms (including a custom 404 page)

What do you exactly mean by this? 😅 A link to an external page, an html response, etc.?

some content we display as 404 page
