Error on MessageBag::has()

I have simple message alerts on the page for various actions. It's look like this

@if(Session::has('message'))
    <div class="alert alert-info"></div>
    <hr />
@endif

From another thread here on SO which was resolved I've tried to count them

@if(count(Session::has('message')) > 0)
    <div class="alert alert-info"></div>
    <hr />
@endif

but still I get this error

Missing argument 1 for Illuminate\Support\MessageBag::has(), called in /var/www/html/site/vendor/laravel/framework/src/Illuminate/Support/ViewErrorBag.php on line 92

What is this means and what is this argument which is missing?

Update: As I said I have tried this and you can see it in my question. @if(count(Session::has('message')) > 0)
