Cypress says script error thrown in cross origin script - do not know why

Hello!

Everything works ok. 0 errors in Chrome or in tests console. But I get this error. And all pipeline is broken.

If there is a error, why it is hidden from me?

Uncaught Error: Script error.

Cypress detected that an uncaught error was thrown from a cross origin script.

We cannot provide you the stack trace, line number, or file where this error occurred.

Check your Developer Tools Console for the actual error - it should be printed there.

It's possible to enable debugging these scripts by adding the 'crossorigin' attribute and setting a CORS header.

This error originated from your application code, not from Cypress.

When Cypress detects uncaught errors originating from your application it will automatically fail the current test.

This behavior is configurable, and you can choose to turn this off by listening to the 'uncaught:exception' event.

@hiren0007 I’m not totally sure why this is displaying as a ‘cross origin error’. It looks like there is an error in Harpers own code trying to console.log() an undefined variable when the window loads. Perhaps I’m wrong about it not being from a cross origin script though 🤔

If this is not your website and you cannot fix the error, I suggest adding a check to ignore uncaught errors in Cypress like below:

Cypress.on('uncaught:exception', (err, runnable) => {
  // returning false here prevents Cypress from
  // failing the test
  return false
})

it('fails to visit website 1', function () {
  cy.visit('https://harper-morpho-luna.myshopify.com')
})

Hello. Interestingly, this workaround (bypassing uncaught errors) work in the open ui, but still fail in terminal/cli! And when I simply return false for that listener, it locks hanging the terminal, never ending the tests.

Any reason for that?!
