Unable to autoload constant ActiveStorage::Blob::Analyzable - ruby-on-rails

Question

I looked at every possible solution regarding this error but nothing solved it.
Every time I try to upload an image, I receive this error:
Unable to autoload constant ActiveStorage::Blob::Analyzable, expected /usr/local/lib/ruby/gems/2.5.0/gems/activestorage-5.2.2/app/models/active_storage/blob/analyzable.rb to define it.

In config/application.rb I have require 'active_storage/engine' uncommented.
In config/environments/development.rb I have config.active_storage.service = :local set up.
I ran rails active_storage:install and rails db:migrate.
The name of the model is user_test
class UserTest < ApplicationRecord
has_one_attached :image
end
I have this in app/controllers/user_tests_controller.rb
def user_test_params
params.require(:user_test).permit(:title, :caption, :image)
end
**config/storage.yml*
test:
service: Disk
root: <%= Rails.root.join("tmp/storage") %>
local:
service: Disk
root: <%= Rails.root.join("storage") %>
I am really clueless as to why it isn't working.

Answer 1

Do you have config.active_storage.service = :amazon set in your development.rb by any chance?
I was getting the above error and it ended up being because I had the above line but the AWS env vars weren't set.

Answer 2

Make sure you check that all of the environment variables present:
AWS access key
AWS secret key
Bucket Name
checking spelling of the environment variables to make sure they match your storage.yml configuration file
