WCT: "TypeError: Cannot read property 'match' of undefined"

[super-kamil]

Hi, suddenly the tests stopped working.

TypeError: Cannot read property 'match' of undefined

Tried different node versions. Same error. Any idea how to debug this to get additional information?

Windows 11
command: wct --npm

wct.conf.json But the error is alway the same. No matter which config.

}

Browser object:

browser {
  name: 'chrome',
  path: 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe',
  binPath: 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe'
}

Version property is missing.

@super-kamil so what exactly was the fix?

[chiragshivam]

Do we have any fix for this yet?
I could see that while installing the web-component-tester module, it tries to install launchpad from forllowing commitin the package.json
"dependencies": {
"@types/express": "^4.0.30",
"@types/freeport": "^1.0.19",
"@types/launchpad": "^0.6.0",
"@types/which": "^1.3.1",
"chalk": "^2.3.0",
"cleankill": "^2.0.0",
"freeport": "^1.0.4",
"launchpad": "git+https://github.com/web-padawan/launchpad.git#fdd994d089572e2c2152d70cc74abf497d08d5b7",
"selenium-standalone": "^6.7.0",
"which": "^1.0.8"
}

was there any specific reason for this?
Am I missing something here?
