Dynamic Routes keep prompting error on not founded item (not 404)

How to get 404 instead of 500 error on not found item?

eg

// This function is required to generate static parameters for each user ID.
export async function generateStaticParams() {
  // Mock data: Replace with your actual data source
  const users = [
    { userID: '1' },
    { userID: '2' },
    { userID: '3' },
  ];

  // Generate the params object for each user ID
  return users.map(user => ({
    params: {
      userID: user.userID
    }
  }));
}

export default function UserIDPage({ params }) {
  return <>User ID Page: {params.userID}</>;
}

I got 500 error to access /users/4 path, would expected 404 page.

my current error message is

Error: Page "/users/[userID]/page" is missing param "/users/4" in "generateStaticParams()", which is required with "output: export" config.

I need share some story, I created project from CreateReactApp then install next... not sure where is the root cause for the static param issue.
