gzip an image file

[NandoSangenetto]

Hello,

I'm getting some an error when I try to run a gulp script with gulp-connect and connect-gzip.
The problem is when I try to gzip an image file, the image is gziped and sent to the browser, but the server crashes.

This is my code:

const connect = require('gulp-connect'),
      connectGzip = require('connect-gzip');

gulp.task('connect', function() {
  connect.server({
    root: 'public',
    livereload: false,
    port: 8080,
    middleware: () => {
      return [
        connectGzip.gzip({ matchType: /text|javascript|json|image/ })
      ];
    }
  });
});

This is the error:

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: write after end
