Missing browserCriClient in connectToNewSpec #27657

joshkaplan · 2023-08-24T19:51:54Z

Current behavior

Sometimes when running tests (in CD, in docker), cypress simply fails.

We see:

Timed out waiting for the browser to connect. Retrying...
Error: Missing browserCriClient in connectToNewSpec

And then cypress.run returns:

{
  "failures": 1,
  "message": "Could not find Cypress test run results"
}

Notes:

we are running using the module api.
We are also using --quiet
It happens lot in 1 project in particular (~50% of the time):
- For this project, it happens in the same place every time: after the first spec in the project has completed, and before the second spec has started
- The first spec passes, and everything looks fine in the video
It also happens sporadically in other projects (3-4% of the time)

Desired behavior

tests to run without crashing (or some indication of what is being done incorrectly)

Test code to reproduce

unsure how to reliably reproduce. most projects run fine most of the time.

Cypress Version

12.17.3

Node version

16.20.0

Operating System

Looks like the same problem as #27241 and #24650

here's a couple of snippets from the debug output with DEBUG=cypress*

can't share the entire thing here, since it's huge and contains sensitive info. if there are select modules we should capture, could try that.

note that "sem-pages" is the 2nd spec in this project

it's clear that cypress is killing the browser: cypress:server:browsers killing browser process, but not seeing any particular reason why, or how we can prevent it

joshkaplan · 2023-08-28T17:12:45Z

updates:

we noticed that a test in the first spec was clicking on a link with target set to _blank, opening in a new tab.
removing this click() seems to have mitigated the issue
it is still happening sporadically on other projects, ~ .5% of the time

hopefully that can maybe help narrow in what might be going on.

some outstanding questions:

is this expected behavior for new tabs?
- if so, it ought to (1) fail more loudly and more explicitly, (2) be documented, and (3) ideally there would be a way to globally handle this
- if not, what's going on here?
why might it be happening sporadically?

stfnzl · 2023-09-02T07:20:58Z

Experiencing this issue as well.

Setup:

Cypress ^12.17.0 as per Missing browserCriClient in connectToNewSpec #24650
Cypress Cloud
Chrome 99 headless
The whole thing runs in a docker container

In another project this issue does not exists. Same pipeline setup but:

Cypress 12.8.1
No Cypress Cloud
Chrome 99

Would any of the following help?

Upgrade Chrome
No docker, run raw on the vm

stfnzl · 2023-09-02T18:56:03Z

Quick update from my side:

Updated chrome
No docker, run raw on the VM
Gave the VM more RAM

Do not see any issue anymore...

Dospios · 2023-10-05T21:29:16Z

I have the same problem.

Cypress v13.2.0
Chrome v117
No cypress cloud.
Run tests via LXC

There is no stable 100% STR, the problem is only on CI, in about 10-20% of cases.

After RAM was increased, the problem began to appear a little less often, but it did not disappear completely.

I hope you solve this problem or tell a workaround, this problem makes our ci tests unstable

Dospios · 2023-10-19T21:03:54Z

Any update?

stfnzl · 2023-10-21T19:06:54Z

@Dospios I did some experimenting and it seems like that setting

export NODE_OPTIONS=--max_old_space_size=8192

did help a lot.

I also set numTestsKeptInMemory: 1 in cypress.config.js but max_old_space_size is something you want to try.

Dospios · 2023-10-21T21:24:48Z

@stfnzl
I already set max_old_space_size=8192 in NODE_OPTIONS when starting cypress and in js-flags in arguments when starting chrome.
numTestsKeptInMemory: 0
I also clear the memory after every third test using Cypress.automation('remote:debugger:protocol', { command: 'HeapProfiler.collectGarbage' }). The maximum memory consumption at the time of the crash does not exceed 3gb.
None of this helped, unfortunately.
Also, sometimes before the error Missing browserCriClient in connectToNewSpec another one began to appear - cypress:launcher:browsers chrome stderr: [1020/143746.177548:WARNING:sqlite_persistent_store_backend_base.cc(198)] Failed to post task from FlushAndNotifyInBackground@net/extras/sqlite/sqlite_persistent _store_backend_base.cc :246 to client_task_runner_.

stfnzl · 2023-10-22T04:13:00Z

@Dospios just for curiosity, do you run cypress and the web server in the same host?
Meaning do you run cypress against http://localhost or against an external url?

Dospios · 2023-10-22T10:29:59Z

@stfnzl external url. For each PR, a test stand is deployed, on which autotests are run and manual testing is carried out

stfnzl · 2023-10-23T06:04:18Z

@Dospios thanks for the info. I asked 'cause we run against localhost and wanted to check if separating cypress/chrome and the webserver would have helped, but it is not the case seems like so not gonna spend time on setting it up.

I did a "stress test" on our setup by running 20 builds in azure devops which trigger 3 parallelized jobs each (~60 cypress runs)
and I got 2 Missing browserCriClient in connectToNewSpec, the remaining are green.

3.3% failure rate is still too high imo... my goal is to have at least 100 consecutive stable runs (<1% failure rate)

...and the fact that cypress cloud will not report it as failure but rather as a timeout does not help either 😞

abinaya-konda · 2023-11-13T19:40:32Z

any update on this? I keep getting this issue consistently while executing the last test on the CI/CD pipeline and nothing seems to fix this. It makes the test unusable!

stfnzl · 2023-11-14T10:49:36Z

We have different projects running Cypress without any issues, but the only one that is failing with
Error: Missing browserCriClient in connectToNewSpec has the most tests (~250)

Do you experience the same @abinaya-konda @Dospios?

I'm thinking to split the tests in 3 or 4 groups and see if it helps or not...

Dospios · 2023-11-14T11:10:55Z

@stfnzl Also have 200+ isolated tests that run in parallel. But I noticed that the browser can crash even on 1-5 specs at the very beginning of the run.
I wrote a crutch that allows you to automatically retrain the job to ci if browserCriClient is present in stdout, starting the job again in this case, but this is just a crutch, not a solution to the problem

abinaya-konda · 2023-11-20T09:58:11Z

@stfnzl - I have around 150 tests running, and it always seems to fail at the last spec file. If I skip or remove it, the issue pops up at the new last spec file. Now this happens around 80% of the tests that I have removed cypress test suite from the pipeline for now!

jazpearson · 2024-01-11T13:30:51Z

One thing that i did was to switch to using Edge as the browser. I've barely seen this issue since, whereas before the switch, we were seeing something like 30-40% of test runs fail.

timollet · 2024-01-19T15:01:26Z

Hey,

SerdarNur · 2024-06-06T08:07:54Z

Are here any updates or solutions? @jennifer-shehane @mschile @AtofStryker

jennifer-shehane · 2024-06-07T14:30:38Z

We have gotten some DEBUG logs with more specifics that we're looking into. It looks like this error started around 11.0 in Cypress, but is maybe happening more frequently lately due to some other change.

AtofStryker · 2024-06-10T21:32:03Z

OK I am able to reproduce this. Its similar to #28397. The logs provided suggest that the browser is exiting mid run (I don't want to say crash because the exit code is 0). When that happens, we wait for the browser to reconnect up to 3 attempts. In this case though, since the browser closed, we closed the CRI client as well and we are able to successfully relaunch the browser, expecting the CRI client to be there, but its not so we get this error. I can reproduce it with this branch against this test suite. I will start exploring solutions shortly...
