Cloudinary only works locally and not in production

I have a problem with deploying my app on heroku ... it's been several hours since I tried to use Cloudinary with my Heroku app.

I followed literally different tutorials from Cloudinary.

EDIT When I download photos on my local app, i find them on Cloudinary ! How to make it also on my Heroku app ? :/


# paperclip
gem 'paperclip'
gem 'paperclip-cloudinary'


  cloud_name: hoxr8ugj3
  api_key: 'xxx'
  api_secret: xxxx
  enhance_image_tag: true
  static_image_support: true


class Photo < ApplicationRecord
    belongs_to :projet

    has_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>" }
    validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/ 


    :storage => :cloudinary,
    :path => ':id/:style/:filename'

Everything works perfectly locally ... I do not understand! :(

With git push heroku master, i get this warning You set yourconfig.active_storage.serviceto :local in production.

I probably need to change some things in storage.yml ? or create secret.yml ? but how ?


  service: Disk
  root: <%= Rails.root.join("tmp/storage") %>

  service: Disk
  root: <%= Rails.root.join("storage") %>

I also tried :

heroku config:add CLOUDINARY_URL=....

heroku logs error :

Thank you very much for your help and sorry for my english.
