gulp-sassport throws an error

[iamnewton]

Wasn't sure if I should submit ticket here since the errors are pointing to sassport. I should note that I'm using Gulp v4 and I've removed everything but the sassport part of the task and I just get a Segmentation fault: 11 error.

// gulpfile.js
'use strict';

const autoprefixer = require('gulp-autoprefixer');
const changed = require('gulp-changed');
const flexBugsFixes = require('postcss-flexbugs-fixes');
const postcss = require('gulp-postcss');
const sass = require('gulp-sass');
const sassport = require('gulp-sassport');
const sourcemaps = require('gulp-sourcemaps');

module.exports = (gulp, options) => {
    const files = `${options.dirs.source}/${options.files.scss}`;
    let outputStyle = 'expanded';
    if (options.environment !== 'development') {
        outputStyle = 'compressed';
    }
    const processCss = () => gulp.src(files)
        .pipe(changed(`${options.dirs.dest}/${options.files.css}`))
        .pipe(sourcemaps.init())
        .pipe(sassport([], {
            outputStyle,
            includePaths: [
                'node_modules/',
            ],
        }))
        .on('error', sass.logError)
        .pipe(autoprefixer({
            replace: true,
            cascade: false,
        }))
        .pipe(postcss([flexBugsFixes]))
        .pipe(sourcemaps.write('./'))
        .pipe(gulp.dest(`${options.dirs.dest}/styles`));

    gulp.task('css', processCss);
    gulp.task('css').description = 'Node.js bindings to libsass. <https://github.com/sass/node-sass>';
