Images are not uploaded only when updated

Prerequisites/What you want to achieve

I'm creating an app with Ruby on Rails.
There is a model that allows you to register images, but once you delete the image and start with nothing, you can register the image normally.
Once an image is registered and updated to change to another image, the image disappears and is new
The image you want to register has not been uploaded.
I have never experienced this situation since I have created several apps in the same way, and I think the settings are different from the ones I created before, but I've looked around the settings, but I'm in trouble because it doesn't heal at all.
Could you please let me know if there is anyone who seems to understand that this area is suspicious?
If there is a lack of information, please let me know.Thank you for your cooperation.

Tried

If you run it on the development environment (Cloud 9), you can update the image successfully (because you are not using Cloudinary).
I was wondering if Mini Magick was not good, and once I deleted and updated Mini Magick, the situation remained the same.
The situation remained the same when I remade it in Rails 4.2.5.
Re-create the Heroku app, add Cloudinary as a new add-on, and add CLOUDINARY_NAME, CLOUDINARY_API_KEY, etc.
I registered with Heroku again, but it didn't go away.
