Describe the Bug

Vercel changed the default timeout to 15 seconds at the beginning of October.
Now some of my functions are timing out.

I cant seem to find a way to actually set the maxDuration of my Astro Routes.
My functions are just Astro APIRoutes living under /pages/api/..

What's the expected result?

Being able to set the maxDuration

What causes the responses to take so long?

Does it really matter? I could think of multiple use cases where I would to be able to define a longer maxDuration

[lilnasy]

I think so. If it is because of some user code, then it might be better handled by user code as well.

How would this need a repro?

[lilnasy]

If it is not a bug with a repro, it might be a feature request, which could benefit from an explanation of a use case, and how Astro could help.

Do you want to show a custom 504 page when the function times out?

After looking at Vercel docs, I see what you mean: maxDuration is a vercel option.

We do not have a way to set platform-specific configurations yet, but it is being tracked as a feature request here:

• Export a page config for granular adapter configuration roadmap#656

Since being "granular" is not necessary for maxDuration, it can be implemented right away!
