Grunt fails on the mac with nodejs 21.1.0 version

[nareshgundu23]

we are trying to grunt after the npm install, but in gruntfile.js we have below piece of code. I don't see any permission issues with project directories or files. and same this works in the windows machine without any issues

copy: {
            main: {
                files: [
                {
                        expand: true,
                        mode: true,
                        cwd: './',
                        src: ['./**/*', '!./workspace/**/*', '!./nw/nw_mac/**/*'],
                        dest: 'build/'
                    },
                    {
                        src: './install_config.js',
                        dest: 'build/ugs/lib/'
                    }
                ]
            },
