title: Laravel - Driver [] is Not Supported
body: <p>I haven't found an example like mine, the others appear to be missing what I already have but anyways, I'm trying to upload to an external FTP site, to which I have the following in my filesystem.php file:</p>
  
  <pre><code>    's3' =&gt; [
          'driver' =&gt; 's3',
          'key' =&gt; env('AWS_ACCESS_KEY_ID'),
          'secret' =&gt; env('AWS_SECRET_ACCESS_KEY'),
          'region' =&gt; env('AWS_DEFAULT_REGION'),
          'bucket' =&gt; env('AWS_BUCKET'),
      ],
  
       'fourkites-ftp' =&gt; [
          'driver' =&gt; 'ftp',
          'host' =&gt; 'ftp.site.com',
          'username' =&gt; 'my-username',
          'password' =&gt; 'my-password',
  
      ],
  </code></pre>
  
  <p>And I'm trying to send the file along with the following in one of my controllers:</p>
  
  <pre><code>  Storage::disk('fourkites-ftp')-&gt;put('new/afnloads.csv', $temp);
  </code></pre>
  
  <p>And as I'm trying testing it, it gives me this error:</p>
  
  <pre><code>(1/1) InvalidArgumentException 
  Driver [] is not supported.
  in FilesystemManager.php line 126
  </code></pre>
  
  <p>Are there any suggestions? Thanks!</p>
