Cypress Cloud only: shows the "404" page for NextJS dynamic routes with 'force-static'. How to debug?

[IonelLupu]

I have a NextJS app and a couple of e2e tests. All the tests that hit the pages that are under a dynamic route name and contain export const dynamic = 'force-static' return the "not found" page. The same exact page (with the same exact source code) that is not under a dynamic route work correctly in cypress cloud.

One note: all the tests pass when running on my local machine.

For example, here is the file tree of my project:

app
└── hotels
    ├── [id]
    │   └── [slug]
    │       └── page.tsx  // tests fail for this page on cypress cloud only
    │   ├── another
    │       └── page.tsx  // tests fail for this page on cypress cloud only
    ├── another
    │   └── page.tsx  // tests pass here
    └── test
        ├── [test]
        │   ├── another
        │   │   └── page.tsx  // tests fail for this page on cypress cloud only
        │   └── another
        │       └── page.tsx   // tests pass here

The test suite is very simple:

context(`some test context`, { tags: ['@mobile', '@desktop', '@developmentApi'] }, () => {
    it('home page', () => {
        cy.visit('/')
        cy.contains('Hello world')
    })
    it('hotel slug another', () => {
        cy.visit('/hotels/18923395/another')
        cy.contains('Hello world')
    })
    it('hotel another', () => {
        cy.visit('/hotels/another')
        cy.contains('Hello world')
    })
    it('hotel test another', () => {
        cy.visit('/test/another')
        cy.contains('Hello world')
    })
    it('hotel test slug another', () => {
        cy.visit('/test/random/another')
        cy.contains('Hello world')
    })
    it('hotel original', () => {
        cy.visit('/hotels/18923395/Hotel-Parador')
        cy.contains('Hello world')
    })
})

export {}

With all of these, those 3 tests fail to pass on Cypress Cloud only saying the page was not found:

And every page.tsx content is this:

import React from 'react'

export const dynamic = 'force-static'
export const revalidate = 1800

export default async function HotelPage() {
    return <>Hello world</>
}

How can I debug this in cypress cloud? I don't have access to the NextJS server to see the logs

Edit

After days of debugging, it seems building the project with NODE_ENV=test is the real issues: vercel/next.js#58935
