After deploying a app with Next.js & AI SDK, streaming response occured "Unhandled Promise Rejection: Error: Connection closed."

I write an App using Next.js & AI SDK, the details as following:

Next.js: 14.2.3
Vercel AI SDK: 3.1.22

I have a OpenAI assistan which it will return a long response. I upgraded from Hobby to Pro, and added the following configuation(accorging to https://sdk.vercel.ai/docs/troubleshooting/common-issues/streaming-not-working-on-vercel-pages-router) in my actions file:

export const dynamic = 'force-dynamic';
export const maxDuration = 120;

Like AI SDK Demo, the action defained out of the "src/app/api? directory but "src/actions/server/chat.tsx", and it can not work!

How can I do ? Thanks.

BTW, it is the log message of project's dashboard,

it is the deafault max duration of Pro.

Solved！

Using https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config ，

export const maxDuration = 5
