Shopify_app: undefined method `storage' for ShopifyApp::SessionRepository:Class

[prativapokhrel]

I updated shopify_app gem to the latest version(13.0.0) and while starting the server I got this error
undefined methodstorage=' for ShopifyApp::SessionRepository:Class (NoMethodError)
Did you mean? shop_storage= `

I have a initializer called shopify_session_repository.rb

if Rails.configuration.cache_classes
  ShopifyApp::SessionRepository.storage = Shop
else
  reloader = defined?(ActiveSupport::Reloader) ? ActiveSupport::Reloader : ActionDispatch::Reloader

  reloader.to_prepare do
    ShopifyApp::SessionRepository.storage = Shop
  end
end

This is the one throwing the error.

I tried using ShopifyApp::SessionRepository.shop_storage = Shop

And got this error:
* ArgumentError Exception: shop storage must respond to :store and :retrieve
But, I have include ShopifyApp::SessionStorage in my Shop model

Could you please help me with this!

You should be able to get rid of your custom initializer in your app. Now you can just add

ShopifyApp.configure do |config|
  config.shop_session_repository = 'Shop'
end

And also make sure to change include ShopifyApp::SessionStorage to include ShopifyApp::ShopSessionStorage in your Shop model.

There is a migration guide in the README for 13.0.0 https://github.com/Shopify/shopify_app#migrating-to-1300
