Cannot read property 'filter' of undefined

Hi there,

Hopefully this is the right place to post this. I'm getting an error that I've never had before and randomly mid-way through a project:

C:\Users\mathew\Documents\Work\builds\www\projectname\node_modules\gulp-svgmin\node_modules\svgo\lib\svgo\plugins.js
:46
        items.content = items.content.filter(function(item) {
                                     ^

I've not changed anything or update any files. Can anyone point me in the right direction?

If I remove the svgmin task itself the build succeeds.

The task looks like:

gulp.task('svgmin', function() {
    return gulp.src('assets/images/svg/*.svg')
      .pipe(plumber())
        .pipe(svgmin())
        .pipe(gulp.dest('assets/images/svg'))
        .pipe(notify({message: 'svgs minified!'}));
});

svg/svgo#432 is the correct place for this discussion. 😄
