Gulp Fontello Erroring with adm-zip, recent phenomenon

Question

I use gulp-fontello in a gulp build script. It's been working for years just fine, until recently I'm getting this error when I run the fontello task:

Error: Invalid filename
    at new module.exports (F:\Websites\olivebranch\wp-content\themes\wpx\assets\node_modules\adm-zip\adm-zip.js:22:10)

[11:22:12] 'fontello' errored after 592 ms

I have dozens of different installs that make use of this task. At first I thought something was changed in node (perhaps a new version of adm-zip?) but it turns out all my old installs fail on the task too. The older installs which haven't been run npm install in the past few weeks:

It seems like a filename has changed inside Fontello itself?

Answer 1

If you are using the host option on your gulp task check the set protocol, it must be https in order to work as expected

const gulp = require('gulp'),
  $ = require('gulp-load-plugins')();

const options = {
  host : 'https://fontello.com',
  font : 'font',
  css : 'css'
};

gulp.task('fontello', function () {
  return gulp.src('config.json')
    .pipe($.fontello(options))
    .pipe(gulp.dest('dist'))
});

if you're not using any options, try to set the host like that

return gulp.src('config.json')
    .pipe($.fontello({host: 'https://fontello.com'}))
    .pipe(gulp.dest('dist'));
