I am using this package.

https://php-flasher.io/laravel/

This code of mine works fine.

 flash()->success('Operation completed successfully.');
        return back();

But

<script>
            @if ($errors->any())
                @foreach ($errors->all() as $error)                 
                    flasher.error("{{$error}}");
                @endforeach
            @endif
</script>

but it doesn’t show these error messages
