Cannot read property '0' of undefined about gulp-stylelint HOT 12 CLOSED

Ok, will try to prepare it tomorrow.

from gulp-stylelint.

I'll up to 7.3.1 first thing tomorrow morning. Too much beer today... sorry for delays...

I didn't actually expect it to work with gulp 4 at all. However it seems to work fine. I've created a test repository here: gulp-stylelint-test. Can you try to clone, npm install, npm run lint it?

from gulp-stylelint.

Thanks for providing the test-case! I tried it and it works. Unfortunately in my case it doesn't and I'm still wondering why. I will investigate further occasionally, but feel free to close this issue.

Let's keep it open for the time being, I'll do some investigation on my side as well.

Hi. I am having the same problem. Problem occured when I updated plugin from version 2.0.2 to 3.1.0.

This is my error:

Cannot read property '0' of undefined
Stack:
TypeError: Cannot read property '0' of undefined

This is gulp code inside pipe:

stylelint({
    reporters: [
        {formatter: 'verbose', console: true}
    ],
    debug: true
}

Gulp version:

CLI version 3.9.1
Local version 3.9.1

Hope this helps in anyway finding the bug.

Isn't it weird that the error gets thrown from jsonFormatter when you're using verboseFormatter? Also, what is stylelint in your code: stylelint or gulp-stylelint?

from gulp-stylelint.

I tried switching to string, but I got the same error. I tried also something like this, but again same error.

stylelint({
    config: {
        extends: 'stylelint-config-standard'
    },
    reporters: [
        {formatter: 'string', console: true}
    ],
    debug: true
})

Please note that stylelint in code is actually gulp-stylelint. I am using gulpLoadPlugins, so that I don't need to write gulp-* every time 😄 Stylelint is not in my package.json only gulp-stylelint.

I'm under the impression that this is not the code that generates the error. That would explain the reason the error is thrown from jsonFormatter which is not mentioned in your code. Sorry for being naive, but if you comment out the code you provided, does the error go away?

If you can create a small reproducible test case (you can make a pull request to gulp-stylelint-test if you wish) that would help a lot.

This looks like a bug in stylelint 7.3.0. It will be fixed in 7.3.1.
stylelint/stylelint#1914

I would suggest to fix the stylelint dependency to ~7.2.0 until 7.3.1 is released.

from gulp-stylelint.

Version 3.3.0 pointing to stylelint 7.3.1 has been released and published to npm.

from gulp-stylelint.

I'm assuming this has been resolved by the latest release.
