Current behavior

I have a suite of tests that use a before each statement.
On running the tests using the webkit plugin the before each runs then the first test runs.
When the before each runs again it fails before it can get to the second test.

Producing a "expecting an array or an iterable object but got [object Null" error.

The stack trace produced is:

TypeError: expecting an array or an iterable object but got [object Null]

Because this error occurred during a `before each` hook we are skipping the remaining tests in the current suite: `CDS Pages`

It should be noted that this issue only occurs when running against webkit not against chrome, edge or safari

Desired behavior

Cypress runs the tests as per the other browsers without erroring.

Test code to reproduce

describe('CDS Pages', () => {

  beforeEach(() => {
    cdsLoginPage.navigatecds(webpage)
    cdsLoginPage.addUsercredentials(user credentials)
    cdsLoginPage.signIn()
    cdsAccountPage.accountcds(an account)
    cdsAccountPage.switchincds(an account, text)
  })
})

Do you have experimentalSessionAndOrigin enabled? Try removing this flag and running again, experimentalWebkitSupport does not support experimentalSessionAndOrigin yet.

Going to close as duplicate of #23832

Could you provide a reproducible example? I won't be able to investigate further without one as there isn't enough information for me to go on.

@agoodall77 We understand that you wouldn't want to share any IP with us, but if you could create a sort of trimmed-down example of the project (preferably in a repository) that triggers this error so that we can re-produce the issue on our machines, that would be extremely helpful. Thanks!

This looks like #23832. Thanks for the repro @agoodall77, I'm going to close this issue since it is a duplicate. You can watch #23832 for updates on this.
