Error: No connection to WebDriver Bidi was established – Only in Docker (CodeceptJS + Selenium Grid)

[myrepojuly]

We are encountering the following error when executing tests inside a Docker container using the selenium/standalone-chrome image.

The same tests run without any issue locally:

Error: No connection to WebDriver Bidi was established
...
Error: connect ETIMEDOUT 172.17.0.2:4444

Environment Details:

Node.js Version: 22.15.0
CodeceptJS Version: ^3.7.3
WebdriverIO Version: ^9.15.0
Docker Image: selenium/standalone-chrome:134.0.6998.165-20250525

Config:

[kobenguyent]

out of curiosity, does it work if you change host to 172.17.0.2

export const config: CodeceptJS.MainConfig = {
  tests: './*test.ts',
  output: './output',
  helpers: {
    WebDriver: {
      url: 'https://github.com',
      host: '172.17.0.2', <<<<<<<<< instead of localhost
      port: 4444,
      path: '/wd/hub',
      browser: 'chrome',
    }
  },
  include: {
    I: './steps_file'
  },
  name: 'codeceptjs_Check'
}

[myrepojuly]

Hi @kobenguyent Unfortunately, it still doesn't work.

With CodeceptJS v3.7.3 and WebdriverIO v8.44.1, the issue seems identical to CodeceptJS issue #4849.

With CodeceptJS v3.7.3 and WebdriverIO v9.15.0, it appears similar to WebdriverIO issue #14389.

What’s particularly surprising is that it works perfectly with CodeceptJS v3.6.9 and WebdriverIO v8.44.1, but breaks with v3.7.0 and above.

Please let me know if you need any additional logs

[kobenguyent]

With CodeceptJS v3.7.3 and WebdriverIO v8.44.1, the issue seems identical to #4849.

this just gives me one thing.

may you try bidiProtocol: true in config?

[myrepojuly]

I also tried running with both:

bidiProtocol: true

bidiProtocol: false

But no luck — the issue persists in both cases.

Here are the Docker container logs when running with bidiProtocol: true

Not sure if I am missing anything with Codeceptjs version 3.7.3

[kobenguyent]

would you mind creating a minimal repo which we could try to reproduce and check if we could learn something from there?

[myrepojuly]

Sure, I’ll share the repo by EOD today for easier reproduction

[myrepojuly]

Hi @kobenguyent Here’s the sample repo: https://github.com/myrepojuly/codecetpjssample

I’ve added the steps to reproduce the issue in the README.md file.

Let me know if you need anything else.
