Paperclip w / Imagemagick, Amazon S3, and Heroku - Imagemagick & S3 work, but Paperclip fields are not set in the database. Works great in dev

Question

I am using Paperclip with Imagemagick in my application using Amazon S3 for storage. Everything works great in development. But in Heroku production, it doesn’t work properly.

The image is uploaded to Amazon S3, and sketching works, so the compilation part of Paperclip, Imagemagick, and S3 works fine. But for some reason, the fields of a specific paper clip model are not populated:

imagestore_file_name: 
imagestore_content_type: 
imagestore_file_size: 
imagestore_updated_at: 

In development, they are all populated, but not produced on Heroku. When I try to display the image in a working application (Heroku), it says that it is missing, although it is definitely present on S3. What can cause this error? Thanks for reading.
