Cannot read property isAttached of undefined #6813

EtienneBruines · 2020-03-23T13:09:00Z

Current behavior:

Cypress does NOT work for Firefox 75.

  1) Receiving a project-message "before each" hook for "when multiple tabs are open":
     TypeError: Cannot read property 'isAttached' of undefined

Because this error occurred during a 'before each' hook we are skipping the remaining tests in the current suite: 'Receiving a project-message'

Desired behavior:

No errors.

Test code to reproduce

Any test consisting of more than one it-clause. Firefox crashes upon GC collection afterwards.

Currently there's no Firefox 75-Cypress-docker image available yet, so no forked test was linked.

Example:

/// <reference types="cypress" />
describe('page', () => {
  it('works', () => {
    cy.visit('https://example.cypress.io')
  })
  it('still works', () => {
    cy.visit('https://example.cypress.io')
  })
})

Versions

  │ Cypress:    4.2.0                                                                             
  │ Browser:    Custom Firefox Developer Edition 75 (headless)       
 OS: Linux-based

The text was updated successfully, but these errors were encountered:

jennifer-shehane · 2020-03-24T07:08:28Z

Yes, I can confirm this is happening

❗️Fails in Firefox Develop Edition 75.0b7.
✅Passes in Firefox 72.0.2
❗️Fails during cypress run (headless or headed) - notably this is because runMode auomatically has gcInterval set.
✅Passes during cypress open
❗️Fails when visiting a URL
✅Passes with standard expect assertion without cy.visit()
↺ Test just hangs forever in Cypress 4.0.0-4.0.1
❗️Fails in Cypress 4.0.2+

The error is throwing here:

Workaround

You can set firefoxGcInterval to null for runMode. Note this may have other unintended consequences. Please see our full explanation of firefoxGcInterval here: https://on.cypress.io/configuration#firefoxGcInterval

In configuration file - aka cypress.json

{
  "firefoxGcInterval": {
    "runMode": null,
    "openMode": null
  }
}

Edited by @jennifer-shehane - removed "firefoxGcInterval": null workaround.

EtienneBruines · 2020-03-24T08:40:14Z

Regarding the workaround:

"firefoxGcInterval": null gave me:

TypeError: intervals is null
 Because this error occurred during a 'before each' hook we are skipping the remaining tests in the current suite: 'Test reset password'
   createIntervalGetter/<@http://localhost/__cypress/runner/cypress_runner.js:145972:22

   Async/this.drainQueues@http://localhost/__cypress/runner/cypress_runner.js:160074:14

This one does seem to have the desired effect, not throwing any other errors:

{
  "firefoxGcInterval": {
    "runMode": null,
    "openMode": null
  }
}

jennifer-shehane · 2020-03-24T08:49:17Z

oh, you're right. This is what I get for not running all the code I pasted 😅 Will update my comment and see if this is a separate issue.

jennifer-shehane · 2020-03-24T09:11:55Z

Opened an issue here for firefoxGcInterval: null not being supported #6825

…l flake (#428) * update docker image * update node version to 12.18 * wait for comment to be posted * set firefoxGcInterval to null per cypress-io/cypress#6813 * remove quotes from cypress config * add assertion to fix additional flake * set firefoxGcInterval to null in cypress.json vs circle config * ensure like button click is registered on server

Trying the workaround posted seems to allow me to complete one test but then fails immediately after

  errno: 'ECONNRESET',

How do you set Firefox to headless?
Do the tests run without the headless ?

EtienneBruines · 2020-06-19T14:23:44Z

@jpita pass --headless to the command line to run as headless

According to #6813 (comment) it does not run headed (not-headless) either.

both work fine for me on 4.8.0

Seb-C · 2020-06-24T09:39:21Z

The same error started to happen in GitHub actions 2~3 weeks ago. Before it was running fine. I do not know what changed (same Firefox version, same Cypress version and same commit in my codebase suddenly stopped working).

--headless is not an option for me because I use Cypress to test an extension.

Fortunately "runMode": null fixed my problem for now.

jbrokamp · 2020-07-05T08:33:37Z

The error persists in Cypress version 4.9.0 in combination with docker image cypress/browsers:node12.14.1-chrome83-ff77

…oxGcInterval` settings for `runMode` and `openMode` to null - See cypress-io/cypress#6813 for open issue

jennifer-shehane · 2020-07-07T09:00:19Z

The code for this is done in cypress-io/cypress#7791, but has yet to be released.

We'll update this issue and reference the changelog when it's released.

jennifer-shehane · 2020-07-21T06:08:45Z

The work for this has been moved to #8040 in order to get our pre-5.0 release.
