title: Using multipart/form-data header to upload files using vuejs, laravel, axios causes 401
body: <p>I am trying to upload file using axios library.</p>
  
  <pre><code>axios.post('/images/upload', formData, {
      headers: {
          'Content-Type': 'multipart/form-data'
      }
    }).then( response =&gt; console.log(response))
  </code></pre>
  
  <pre><code>Route::middleware('auth:api')
   -&gt;group( function() {
    Route::post('/images/upload', 'ImageController@store');
  })
  </code></pre>
  
  <p>I get the following error with status code </p>
  
  <pre><code>{"message": "unauthenticated"}
  </code></pre>
  
  <p>The moment I remove the header part i.e. "multipart/form-data", the request goes through, but that's no bueno since I need to send the file as well.</p>
