On development, everything is working fine. i can upload an avatar, images and docs to posts and they stay there.
on production, in heroku. i can upload an avatar, image and docs. and they work and appear. however after a while, they do not show anymore and it says that the url does not exist. however, when i check the database i can see that they are stored properly.
here is my heroku log on the error:
