cy.setCookie() setting the requested cookie in Firefox working locally but not in Docker

[derf-github]

Hi,

I'm using Cypress 7.5.0 and I run my E2E tests in a Docker container based on cypress/browsers:node12.16.1-chrome80-ff73.

The tests have been running on Chrome for a while now. When trying to execute them on Firefox, I've got the following error :

CypressError: cy.setCookie() had an unexpected error setting the requested cookie in Firefox.

When I run the tests locally (outside the Docker container) and use the version of Firefox (90.0) installed on my computer (Ubuntu 18.04), the same code works fine.

In order to authenticate in my application, I retrieve the following cookies :

[
  {
    name: 'XSRF-TOKEN',
    value: '7a8b8c79-796a-401a-a45e-1dec4b8bc3c3',
    domain: 'frontend',
    path: '/',
    expires: -1,
    size: 46,
    httpOnly: false,
    secure: false,
    session: true
  },
  {
    name: 'JSESSIONID',
    value: 'B99C6DD2D423680393046B5775A60B1C',
    domain: 'frontend',
    path: '/',
    expires: 1627566358.621716,
    size: 42,
    httpOnly: true,
    secure: false,
    session: false
  }
]

and then I set them using :

cy.clearCookies();
cookies.forEach((cookie) => {
 cy.setCookie(cookie.name, cookie.value);
});

..... 

The logs keep on going and the tests execute successfully.

I can't get my head around why it works when run locally and fails when run in a Docker container.
Do you have any idea on what I'm missing here?

Thank you.

Edit: Created #20015

This is happening to me also. cy.setCookie("foo", "bar") defaults to the alias of my service container as the domain name. This is correct; in the "cypress/included:9.3.1" container, I run cypress run ... -c baseUrl=https://${SERVICE_ALIAS}.

Seems to me like a perfectly fine use case and effectively prevents our CI from running any Firefox jobs.

    1) "before all" hook for "Project"

  1) Object Pages
       "before all" hook for "Project":
     CypressError: `cy.setCookie()` had an unexpected error setting the requested cookie in Firefox.
> Error: An unexpected error occurred
https://on.cypress.io/setcookie
Because this error occurred during a `before all` hook we are skipping the remaining tests in the current suite: `Object Pages`
Although you have test retries enabled, we do not retry tests when `before all` or `after all` hooks fail

@derf-github the issue has been resolved for me by using a service alias including a dot; see #20015
