title: Class 'League\Flysystem\AwsS3v3\AwsS3Adapter' not found (Laravel + Heroku)
body: <p>connect my laravel 5.4 application in heroku with aws s3 to save and display images that I upload with a dashboard. </p>
  
  <p>In local I have no problem with uploading and viewing the images, even these are stored in the bucket I made. But when I set up aws in heroku to do tests there, I get the error: <strong>Class 'League\Flysystem\AwsS3v3\AwsS3Adapter'</strong> </p>
  
  <p>I already removed and reinstalled the package from composer, I do not know why the error does not appear in my local environment.</p>
  
  <p>thank you very much.</p>
