Cypress / Sinon Stub Help

0. My Question

I'm using Next.js and getting serverside data using getServerSideProps, and it depends on stripe. The data stripe returns dictates the props passed to the page or will result in a redirect.
When I make a fake function to replace stripe, I can stub that as a dependency just fine. But I cannot seem to stub the stripe call. The imported getServerSideProps function will run and just hang when it's supposed to call the stripe stub. I think it has something to do with the fact that stripe is a constructor? The stripe node library has a note about exporting the Stripe constructor to be used with sinon, but I don't seem to be using it correctly.
I've seen the example with window / new Notification in the Cypress github, and tried to recreate it, but that didn't work.

So, my questions are 
- is there a better way to be going about this?
- if not, how do I properly stub a dependency that is a constructor?

2. fakeLibFile.js

export const fakeLibAsync = {
    customers: {
        create: async (customerDetails) => {
            const setTimeoutPromise = timeout => {
                return new Promise(resolve => setTimeout(resolve, timeout))
            }
            await setTimeoutPromise(1200)
            return { id: 2 }
        }
    }
}

3. pageFile.js

import { fakeLibAsync } from '../utilities/fakes.js'
....
export const getServerSideProps = async (context) => {
    try {
      // ..... [when running the stripe test, everything here runs fine]
      
        const options = {
            description: 'My First Test Customer (created for API docs)',
          }
        const customer = await fakeLibAsync.customers.create(options)
        // // what is actually used in application
        // const customer = await stripe.customers.create(options);
        
        
        return {
            props: {
                customerId: customer.id
            }
        }
    } catch (error) {
        console.log("error", error)
        return {
            props: {
                error: true 
            }
        }
    }

}

4. workingTest.js

const { getServerSideProps: gspCustomer } = require('../../pages/stripe-test-customer.js')
const { fakeLibAsync } = require('../../utilities/fakes.js')
....
it('this works to call with fakeLib ASYNC', async () => {
    cy.stub(fakeLibAsync.customers, 'create').resolves({ id: 2 })
    
    const customerProps = await gspCustomer()
    expect(customerProps).to.eql({ props: { customerId: 2 }})
})

5. testDoesntComplete.js

const { getServerSideProps: gspCustomer } = require('../../pages/stripe-test-customer.js')

// tried many stripe imports here
const stripeModule = require("stripe")

const stripe = require("stripe")('test')
const stripe = require("stripe").Stripe('test')
const stripe = new stripeModule.Stripe()

.....

it('test', async () => {
    // tried many stub setups here
    const stripe = cy.stub(stripeModule,'Stripe').returns(stripe);
    cy.stub(stripe.customers, 'create').resolves({id: stripeCustomerId});
    cy.stub(stripe.customers, 'create').returns({id: stripeCustomerId});
    cy.stub(stripe.customers, 'create').callsFake(async () => {
        const setTimeoutPromise = timeout => {
            return new Promise(resolve => setTimeout(resolve, timeout))
        }
        await setTimeoutPromise(1200)
        return { id: 2 }
    });
    
    const customerProps = await gspCustomer()
    expect(customerProps).to.eql({ props: { customerId: 2 }})
})
