node Assertion failed on copy

[ghost]

I think the error speaks for itself:

The config is pretty basic:

    copy: {
      dist: {
        files: [{
          expand: true,
          dot: true,
          cwd: '<%= yeoman.app %>',
          dest: '<%= yeoman.dist %>',
          src: [
            '*.{ico,png,txt}',
            '*.html',
            'images/{,*/}*.{webp}',
            'assets/{,*/}*.*',
            'locale/{,*/}*.*',
            'styles/{,*/}*.*',
            'styles/fonts/{,*/}*.*'
          ]
        }, {
          expand: true,
          cwd: '.tmp/images',
          dest: '<%= yeoman.dist %>/images',
          src: ['generated/*']
        }, {
          expand: true,
          cwd: 'app/locale',
          src: '*',
          dest: '<%= yeoman.dist %>/locale',
        }, {

Seems like a node issue. Does it happen anymore with node.js updated?

[TomBecker-BD]

Happens on my system with latest node.js LTS v10.16.3, grunt 1.0.4.

[TomBecker-BD]

Latest current node.js v12.12.0 also has the issue. Previous major LTS node.js v8.16.2 does not have the issue.
