title: Unable to upload image into AWS. Is there a S3 bucket config issue?
body: <p>New to Apostrophe and I have been following the install guide for servers. I have most things setup and the server is running on Heroku. I've setup the APOS_S3 environment variables but whenever I try to upload an image a entry is generated but when I go to the image URL, I get an error stating key does not exist. I check my bucket and I see that nothing has been uploaded either.</p>
  
  <p>I've tried giving read/write object permissions publicly and it still isn't able to upload. I'm using my root account's Secret and Key as well for the APOS_S3_ variables.</p>
  
  <p>Is there something I'm missing here?</p>
