title: Laravel Driver error - Driver [] is not supported
body: <p>Anyone else had this issue:</p>
  
  <p>I set my filesystems.php config <code>defualt</code> from <code>local</code> to <code>cloud</code> (which is set to my s3) and I get this error with my storage code:</p>
  
  <p><code>$path = $request-&gt;file('avatar')-&gt;store('avatars');</code> -> in my UserController</p>
  
  <p>Error : <code>Driver [] is not supported.</code></p>
  
  <p>If I leave the filesystems config to stock and just run this code the image uploads to my s3 fine</p>
  
  <p><code>$path = $request-&gt;file('avatar')-&gt;store('avatars', 's3');</code> -> in my UserController</p>
  
  <p>shouldnt <code>$path = $request-&gt;file('avatar')-&gt;store('avatars');</code> run to what ever the default is without passing the specific driver? I tried <code>'default' =&gt; 's3',</code> and that gets the same error</p>
  
  <p>CONFIG DRIVERS</p>
