[sonsy-soft]

I use grunt with my .net core
when uglify js files ,I take this error

Uncaught TypeError: Cannot set property 'unobtrusive' of undefined

uglify:
        {
            js:
            {
                src: [
                    'wwwroot/lib/jquery/jquery.min.js',
                    'wwwroot/lib/popper.js/umd/popper.js',
                    'wwwroot/lib/@laylazi/bootstrap-rtl/dist/js/bootstrap.bundle.min.js',
