Next.js 15 server actions throw NEXT_REDIRECT inside try/catch blocks

In Next.js 15 App Router, calling redirect() inside a server action that's wrapped in try/catch throws NEXT_REDIRECT as an error instead of actually redirecting:

async function createPost(formData: FormData) {
  'use server'
  try {
    await db.insert(posts).values({ title: formData.get('title') })
    redirect('/posts')  // throws NEXT_REDIRECT error
  } catch (err) {
    return { error: 'Failed to create post' }
  }
}

The catch block swallows the redirect. Is there a clean pattern for combining error handling with redirects in server actions? Re-throwing NEXT_REDIRECT feels hacky.
