Next.js API routes do not work with amplify.

I followed the procedure "Deploy and host a hybrid app (SSG and SSR)" on the official website below.
https://docs.amplify.aws/guides/hosting/nextjs/q/platform/js#api-routes
※I am using the ap-northeast-1 region.

Deployment was successful and the contents of index.js are displayed correctly.

However, when I run "api/hello", it returns "503 Error ,The request could not be satisfied.

I checked my CloudWatch Logs and got the following error message.

}  

Error (Error: Cannot find module '. /.. I know what the error (Error: Cannot find module '.../.../chunks/400.js') means, but I don't know how to solve it.

Do I need to configure anything in the build or deployment?
