TypeError: Cannot read property 'match' of null

[orelmi]

I get this error when building with gulp.

    .map(function (val) {
     ^

TypeError: Cannot read property 'match' of null

at FSReqWrap.readFileAfterClose [as oncomplete] (fs.js:442:12)

I changed the code like that ( if (val != null) added) and it works fine. Please, tell me why val can be . If the change is correct add it to the repository.

(index.js) at line 104

.map(function (val) {
var last = multipass[multipass.length - 1];
if (val != null)
return val.match(last)[1];
});

Thanks

Can you show me the source file and settings that caused the error to begin with? Was it a sass file using the built-in settings?

[ln-e]

I suppose i have the same problem.
My scss file starts with

@import '../../global/home';
@import url('http://fonts.googleapis.com/css?family=Russo+One&subset=cyrillic');
#page {
  @include gradient-bg(#03254b #012652);
}

And it fails

node_modules/progeny/index.js:106
          return val.match(last)[1];
                    ^

Segmentation fault: 11

But if i change like so

@import url('http://fonts.googleapis.com/css?family=Russo+One&subset=cyrillic');
@import '../../global/home';
#page {
  @include gradient-bg(#03254b #012652);
}

or so

@import '../../global/home';
@import url('http://fonts.googleapis.com/css?family=Russo+One&subset=cyrillic');
.another {
  content: ''; // <- quotes here
}
#page {
  @include gradient-bg(#03254b #012652);
}

or so

@import '../../global/home';
@import url('http://fonts.googleapis.com/css?family=Russo+One&subset=cyrillic');
#page {
  // @include gradient-bg(#03254b #012652);
}

it works.

I have encountered the same problem using sass-brunch.

My scss file starts like this:

@import "compass/reset";
@import "compass/typography/vertical_rhythm";
@import url("https://fonts.googleapis.com/[…]");

This made progeny throw the following error:

error: Compiling of scss/styles.scss failed. TypeError: Cannot read property 'match' of null
  at ./node_modules/progeny/index.js:106:21
  at Array.map (native)

  at SassCompiler.<anonymous> (./node_modules/micro-promisify/index.js:6:10)
  at SassCompiler.compile (./node_modules/sass-brunch/index.js:208:17)

However, when I change the beginning of the file to

@import url("https://fonts.googleapis.com/[…]");
@import "compass/reset";
@import "compass/typography/vertical_rhythm";

or

@import "compass/reset";
@import url("https://fonts.googleapis.com/[…]");
@import "compass/typography/vertical_rhythm";

everything works without problems.

It looks like this error appears when we have only one import from url in file:

//---------------------------------------------------------
// Global UI Styling
//---------------------------------------------------------
@import 'https://fonts.googleapis.com/css?family=Poppins:300,400,500,600,700';

If I add extra import from empty file (I called it "_nothing.scss" and put in the same folder) then the error goes away.

//---------------------------------------------------------
// Global UI Styling
//---------------------------------------------------------
@import 'https://fonts.googleapis.com/css?family=Poppins:300,400,500,600,700';
@import 'nothing';

I've got this too with using sass-brunch, but it happens when I import the gutenberg library. Turms out its config has a conditional import url statement. Thanks @wmnnd and @VladimirKasatkin for helping me figure out that one...

Why do not you try to fix it as follows?

progeny()

↓

progeny({
  multipass: [
    /@import[^;:]+;/g,
    /\s*['"][^'"]+['"]\s*,?/g,
    /(?:['"])([^'"]+)/
  ]
})

Exclude import path including ":"
