Can't verify CSRF token authenticity in Shopify App using Ruby on Rails

[remy727]

I am creating Shopify Rails App from Shopify CLI.

But after selecting the development store, I see APP_UNINSTALLED webhook delivery failed.

I am seeing the following error:

2023-04-08 20:51:16 │ backend │ Can't verify CSRF token authenticity.
2023-04-08 20:51:16 │ backend │ Completed 422 Unprocessable Entity in 1ms (ActiveRecord: 0.0ms | Allocations: 626)
2023-04-08 20:51:16 │ backend │
2023-04-08 20:51:16 │ backend │ ActionController::InvalidAuthenticityToken (Can't verify CSRF token authenticity.):

The versions I am using are:

• Ruby 3.2.2
• Rails: 7.0.3
• shopify_app: 21.4.1
• shopify_api: 12.4

Did anyone have a similar issue before?

I have the same issue. Simply trying to create the app according to https://shopify.dev/docs/apps/getting-started/create#step-1-create-a-new-app

As a result, I cannot preview the app either. When I attempt to open it in preview mode it times out.

I have the same issue in my production environment. No problem in my local environment but when I deploy in production I cannot install the app from the install form.

GET request to /api/auth works fine.
