Error when taking screenshots in afterEach function

[bluepioupiou]

Current behavior:

When i'm trying to take a screenshot in a afterEach method, the first time averything went fine, but when I reload the test the screenshot fails with the following error 👍

TypeError
The following error originated from your application code, not from Cypress.

  > Cannot set property 'err' of undefined

When I refresh again it works and when I refresh it fails, etc. It's not every one of two but almost...

Desired behavior:

I would like to be able use screenshot method in afterEach without issues

Test code to reproduce

/// <reference types="cypress" />

describe("Test", function() {
  afterEach(function() {
    cy.screenshot();
  });

  it("Test", function() {
    cy.visit("http://google.com");
  });
});

Versions

1.4.8

Chrome

@bluepioupiou I'm not able to recreate this with the code provided in Cypress 4.9.0 - Chrome 83.0.4103.116.

• How are you 'reloading' the test?
• Do you have any other code in your support/index.js? plugins/index.js? cypress.json?
• What version of Cypress are you using? cypress info will print this.
• What version of Chrome are you using?

[bluepioupiou]

• Either by using the reload all test button in the interface or by saving again my test file to trigger it
• plugin is brand new I didn't change anything inside, cypress.json is simple :
  { "baseUrl": "http://localhost:3002", "chromeWebSecurity": false, "viewportWidth": 1440, "video": false }
• I juste upgraded to 4.9 and sameresult
• Chrome is at version 83

I'm pretty sure that if I use cypress with command lines everything will be fine but it's a bit hard to develop with the client version if it failed half of the time

[jennifer-shehane]

I'm not sure. We'd have to narrow down why this is failing for you and not me. Maybe it's regional? Something about your google page is loading different from mine? It seems to be indicating this error is throwing from Google somewhere. Are there errors in the DevTools?

[bluepioupiou]

No error from DevTool. A I said it's working too on my side, but only half of the time... did you refreshed ? It works every time ? It reallyis when i'm using screenshot in afterEach. If I use it "normally" in each test it's working fine and I can reload as much as I want

What do you need ? Maybe I can share screen to inquiery more precisly ?
Here is my error in detail:

cypress_runner.js:197680 Console was cleared
cypress_runner.js:197677 TypeError: The following error originated from your application code, not from Cypress.

  > Cannot set property 'err' of undefined

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.

Because this error occurred during a `after each` hook we are skipping the remaining tests in the current suite: Test
