Answer 1

That means that your request doesn't have a user stored on it. So no one is logged in or your session isn't working correctly. $request->user() is a function that runs to try to pull the current user, by default if someone is logged in it will return a user object or a null value I believe. So most likely you are getting a null value back. You could change your if statement to this:
if(!$request->user() || !$request->user()->isATeamManager()) {

i got the solution..
This is working!!
public function handle($request, Closure $next)
{
if ($request->user()) { // This will return null if the user is not logged in, which evaluates to false
if (!$request->user()->isATeamManager()) {
return redirect('articles');
}
}
return $next($request);
}
}
