Missing browserCriClient in connectToNewSpec

[jazpearson]

Current behavior

Unfortunately, this issue is intermittent and only happens in our CI pipeline. But i wanted to see if could raise the issue in case there's something obvious.

We run cypress with the following: cypress-run cross-env NODE_OPTIONS=--max-http-header-size=1000000 cypress run --browser chrome. And we run in a docker container, using the cypress/included images.

This error happens mid-way running through our test suites. Our tests can take 30 minutes, and the following error seems to occur when ending a test suite (or conversely, when starting the next test suite).

Timed out waiting for the browser to connect. Retrying...

When this happens, the test run completely exits and the remaining suites do not run.

Desired behavior

For the test run not to crash

Test code to reproduce

Really difficult to do, sorry. It's intermittent, and it's a fairly large, sensitive, code-base.

Cypress Version

11.0.1

Node version

16.16.0

Operating System

Jenkins CI - CentOS (but runs the cypress docker image)

Debug Logs

No response

Other

We've seen this happening in v10 and v11.

@jazpearson Don't know if this helps but stumbled across this when trying to figure out why our own CI pipeline was breaking with this error message after upgrading agents to 10.11.0. In our case the error was being caused by our test director (sorry-cypress) and ultimately was due to this off-by-one error sorry-cypress/sorry-cypress#613 which has since been fixed.

Hi @jazpearson , I'm sorry to hear you are having problems using Cypress. Unfortunately without a reproducible example, we wont be able to further assist you. If you can figure out a way to reproduce this issue that you can share with us please do comment here and we can reopen the issue.

I am also seeing this error with Cypress 10.11 when running on Jenkins pipeline. This happens very rarely.

Hi @tommy0831 , can you provide a reproducible example that our engineers can use to debug further?

[jazpearson]

One thing i did do was to update these two libraries that i had installed:

• @cypress/webpack-preprocessor from 4.0.3 to 5.15.7
• cypress-terminal-report from 4.1.2 to 5.0.0.

I don't know if it was coincidence or not, but that did help improve things. It still happens, but it's reasonably rare at the minute. Maybe happens 1/20 times, whereas before it was sometimes as bad as 1/4.

I wish i could provide a sample, but i'm under NDA.

This is currently some of our reporting 3rd party components.

    "cypress-mochawesome-reporter": "3.2.3",
    "cypress-multi-reporters": "^1.6.2",
    "cypress-terminal-report": "^5.0.0"
    "mocha-junit-reporter": "^2.2.0"

Happened to me also. Anything new on this issue?

[nagash77]

Hi @matanbanin , We still do not have a reproducible example for our Cypress devs to use to debug this issue. If you can provide one I will reopen the ticket for further investigation.

Hello, I am also seeing this error. I am running my tests locally (not in ci). These are the dev dependencies:
"cypress": "10.8.0",
"cypress-cucumber-preprocessor": "^4.2.0",
"cypress-real-events": "^1.7.1",
"cypress-repeat": "^2.3.3",
"cypress-xpath": "1.6.2"
Below is the error:

I have never seen this error before. All I did was run tests, but today I managed to see it a few times already.

Hi @swatinigam , Do you have a reproducible example by chance? So far no one has been able to provide us with a reproducible example to help us debug this issue. Without being able to reproduce the issue it is extremely unlikely we will find a solution. If you can share one that would allow us to move this ticket forward.

[matanbanin]

It's happening just not reproducible. happens for about 2% of builds

This seems to be the same issue as #22451, however the error is being thrown correctly here, where as it's getting one line of code further in #22451... we had identified it as a mistake on how we are re-launching a browser after the first spec if the browser process is corrupt.

This error is occurs here: https://github.com/cypress-io/cypress/blob/7721e2be9d7cd6695a16385f3a8965625da162c4/packages/server/lib/browsers/chrome.ts
