Downstream imports of cookies() do not make a page dynamic

[SolidAnonDev]

Hi all.

I'm interested in discussing or finding some answers to why imports of cookies() does not result in an async page in the app router becoming dynamic if it's imported in files other than the page in question, but still called for from that page. Unless I am doing something wrong, I am still required to use export const dynamic = 'force-dynamic' in my page in order to have it be dynamic, or the cookie I am calling for will return undefined, as that's what the value may have been when the application was built. All this despite the fact that cookies is imported, but just not directly in the page itself.

It does not appear that this behavior holds true when it comes to layout.tsx pages. These files do not require any specific dynamic marking, and will updating accordingly as the cookies change.

I may be going about this entirely wrong and would like to know if so.

This only happens in production, not in development. It wasn't until I deployed my app that I became aware of this.

The general code in question would look something like the below. I have greatly reduced what I am actually doing to this, and there are reasons that the functionality exists across multiple files that isn't relevant here:

import { getMyCookieValue } from 'other-file';
export const Page = async () => {
    // always undefined without export const dynamic = 'force-dynamic';
    const cookieValue = await getMyCookieValue()
  return (
    <div>{cookieValue.fieldOne}</div>
  )
}

and getMyCookieValue located in a different file:

import { getThisCookieValue } from 'yet-another-file';
const getMyCookieValue = async () => {
    const cookieValue = await getThisCookieValue();
    return cookieValue;
}

and finally getThisCookieValue in yet another file:

import { cookies } from 'next/headers';
const getThisCookieValue = async () => {
    const cookieStore = await cookies();
    return cookieStore.get('cookieValue');
}

As you can see, there is a cookies() import, but it happens a few files over. So I'm not sure why this still wouldn't result in the page becoming dynamic.

Any help on this would be appreciated.
