Increase execution limit for Server Action in NextJS / Vercel?

Question

I have a Server Action in NextJS14 hosted on Vercel. In the Vercel logs I can see the function is timing out:

Execution Duration / Limit.    15.01s / 15s (timed out)

I'm calling the OpenAI API which can be slow. How do I increase the time limit?

Answer 1

You must apply a new max duration inside your top level page.tsx:

export const maxDuration = 90;

export async function Page(){ }

Inside route-segment in next-js docs you can find more information about it.
