Cypress test: Infinitely appended iframe and HTTP error 414 - Request URL too long when Microsoft login, and page load timeout

[dphoenix]

Hello,

I am testing login for a site. The login button redirects to a Microsoft login page when clicked.

Originally I had a frame busting problem, where the test would redirect outside of the Cypress framework, but solved that with the experimentalSessionAndOrigin attribute.

However, now I am facing two new errors.

First, I get an HTTP 414 error, with the URL being too long when Cypress clicks on the button. I noticed that when I looked at the URL in the failure message, it seems that the url seems to have an iframe-request-id query parameter infinitely appended to the URL string, so I see why the URL is too long. I just don't know why that string is appended like that.

I should also note that the URL in the code is generated as an anchor tag, with the href element being a Vue a property.

Also, and I noticed this in a few other tests as well when clicking to a new page, I get a page load timeout error. I can understand that for the infinitely long URL, but my issue is that I set the pageLoadTimeout configuration setting to something insanely big (like 9e+67ms, just to make sure there's enough time). And the timeout error happens after only a second or so. I get this error with another page as well, which is a Vue route, and which does eventually load.

Also, the web portal I am testing is on my local computer, it's a Vue application that is dockerized.

Any ideas about where I start looking? I can't really share a lot of the actual code because it's not mine and kind of private, but I can try to maybe mask some of it.

Thanks!

Try setting experimentalModifyObstructiveThirdPartyCode as described here: https://docs.cypress.io/guides/end-to-end-testing/azure-active-directory-authentication

I'm also having this issue, I've tried setting experimentalModifyObstructiveThirdPartyCode but still getting an infinite redirect with a lot of iframe-request-id query parameters.

I setup a new project and tried visiting the Microsoft Login page. This is where the error seems to be.

Also, there is a discrepency in the documentation about where to put the experimentalModifyObstructiveThirdPartyCode parameter, which one is correct?

https://docs.cypress.io/guides/end-to-end-testing/azure-active-directory-authentication#Configuring-Cypress-to-use-Microsoft-AAD

export default defineConfig({
  e2e: {
    experimentalModifyObstructiveThirdPartyCode: true,
  },
})

https://docs.cypress.io/guides/guides/web-security#Modifying-Obstructive-Third-Party-Code

export default defineConfig({
  experimentalModifyObstructiveThirdPartyCode: true,
})
