Cypress: TypeError: Cannot read property 'replace' of undefined" at Object.appendErrMsg

[James-E-Adams]

Current behavior:

This is a weird issue that is isolated to a single machine.

If I try run a test file with more than one or two tests, I get the following:

The stack trace:

TypeError: Cannot read property 'replace' of undefined

Because this error occurred during a 'before each' hook we are skipping the remaining tests in the current suite: 'bulk actions'

The test spec file like:

describe('tests', () => {
  beforeEach(() => {
    cy.authenticatedVisit(
      'some_url'
    )
  })
  it('draws a box', () => {})
  it('potato', () => {})
  it('draws a circle', () => {})
  it('draws nothing', () => {})
})

and the authenticatedVisit command is:

Cypress.Commands.add('authenticatedVisit', url => {
  cy.visit(url, {
    onBeforeLoad() {
      window.localStorage.setItem(
        'authRefreshToken',
        userJames.authRefreshToken
      )
      window.localStorage.setItem('authAccessToken', null) //it needs this field to have an entry
    },
  })
})

It works perfectly fine on other machines with the exact same set up.

It works fine running a single test at a time - but I'm wondering if anyone else has experienced this before?

Happy to provide any extra info if I can!

Versions

Both cypress 2.1.0 and the previous version. Mac OS 10.13.4, chrome 66.0.3359.139

Can you try adding this to your suite and seeing what the err is here?

Cypress.on('fail', (err, runnable) => {
  debugger
})

Hi @jennifer-shehane!
Sorry for the late response. I couldn't work out where that event listener should go?
I tried it in the spec file at the top, in the describe, in the beforeEach and inside a test.
I also tried it in the console, as well as using cy instead of Cypress.

[James-E-Adams]

@Bkucera I'm not sure if you noticed, but I'm using onBeforeLoad as an option for cy.visit(). If I try to use your suggestion of cy.window() to yield the window inside the onBeforeLoad, I get the attached error, which makes sense, I guess.

[xiankai]

@James-E-Adams I believe you are supposed to put the event listener outside of the describe.

Cypress.on('fail', (err, runnable) => {
  debugger
})

describe('tests', () => {
  beforeEach(() => {
    cy.authenticatedVisit(
    'some_url'
    )
  })
  it('draws a box', () => {})
  it('potato', () => {})
  it('draws a circle', () => {})
  it('draws nothing', () => {})
})

Also Bkucera's suggestion's was to call cy.window() after cy.visit(), not inside onBeforeLoad(). Which means that your authenticatedVisit command would look like this:

Cypress.Commands.add('authenticatedVisit', url => {
  cy.visit(url);
  cy.window().then(window => {
    window.localStorage.setItem(
      'authRefreshToken',
      userJames.authRefreshToken
    );
    window.localStorage.setItem('authAccessToken', null) //it needs this field to have an entry
  });
});

I'm not sure if that would solve your problem but I hope that gives you a working alternative.

I'm getting a similar error in 3.1.5 when trying to cy.setCookie in a before: TypeError: Cannot read property 'replace' of undefined" at Object.appendErrMsg

Inserting that on-fail debugger as you showed yields err = Error and runnable.trace.message = "Error: done() called multiple times" at Hook.Runnable

[jennifer-shehane]

This issue should be fixed as part of this refactor: https://github.com/cypress-io/cypress/issues/3762

Similar to @echurilov I'm unable to call cy.setCookie() within a beforeEach:

Within the Cypress window I see the error TypeError: Cannot read property 'replace' of undefined -

Resolved my issue by trimming the response. Whitespace was being included in the body.

The code for this is done in cypress-io/cypress#5313, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
