setCookie() can't save object anymore

Since upgrading my Cypress to 3.6.0 I can’t set cookies that I need to set for my tests. (The application sets them as well.) I need a way to set the cookie.

Current behavior:

When using cy.setCookie() I get the following error:

CypressError: cy.setCookie() must be passed an RFC-6265-compliant cookie value. You passed:

{"name1":"value1","name2":"value2","name3":"value3","name4":"value4","name5":"value5","name6":"value6"}

(Values have been changed for privacy reasons.)

Desired behavior:

The cookie should be set. It’s the format that is also used by our application.

Steps to reproduce: (app code and test code)

I use the following:

cy.setCookie('cookiename', cookieString, { domain: 'required.domain', });

where

cookieString = {"name1":"value1","name2":"value2","name3":"value3","name4":"value4","name5":"value5","name6":"value6"}

Versions

Cypress 3.6.0

there is another workaround for this:

cy
  .document()
  .then( document => {
    document.cookie = 'cookieName={object: [with, commas]}; expires=Fri, 19 Jun 2020 20:47:11 UTC; path=/'
  });

with this method you can set your cookie in any way you need since this bypasses validations done by Cypress.

Workaround

You can suppress this error by using cy.stub to stub out the Cypress error function.

Add the following to your specs or to your support file:

beforeEach(() => {
  cy.stub(Cypress.utils, "throwErrByPath")
  .callThrough() // still throw other types of errors
  .withArgs("setCookie.invalid_value").returns() // suppress invalid value errors
})
