screenshot and url do not return expected result

[KenjiOhtsuka]

Hello,

I am trying to test OIDC ID provider with test Relying Party site, and I'm struggling to get information after jumping to redirect_uri.
In the following code, click() is a trigger for going to the redirect_uri.
But successive commands, such as cy.screenshot(${SCREENSHOT_DIR}/Redirected page, {capture: 'fullPage'}) and cy.url() fails.

            cy.get('.some-class button[type="button"]').click().wait(10000)

            // Extract authorization code from redirect URI query parameters
            cy.screenshot(`${SCREENSHOT_DIR}/Redirected page`, {capture: 'fullPage'})
            cy.url().then((url) => {
                cy.log(url)
            })            

cy.screenshot says:

(uncaught exception)TypeError: Cannot destructure property 'duration' of 'props' as it is undefined.

when I commented out the screenshot, the cy.url returns blank URL ('').

What I want to do is to check the URL and query parameters (state, code) in the redirected page.

What am I missing? Can't Cypress test 2 or more different domain pages at once?
