Oauth Cookie not returned in redirect_uri

Retired Boards Appdev Authentication

Hi!

I’ve successfully implemented the Oauth flow with a small inconvenience. Before redirecting the user to:
“https://example.myshopify.com/admin/oauth/authorize?client_id=client_id&scope=read_orders&redirect_uri=https%3A%2F%2Fsomething.ngrok-free.app%2Fintegrations%2Fv1%2Fauth%2Fcallback&state=fJISon53weJGZUK&grant_options%5B%5D=”

I set a cookie with the value of the “state” param. This is to later validate the auth callback using:

validate_auth_callback.
Now, when I my server gets the redirect_uri, I don’t receive any cookie. Thus I cannot validate it cause I don’t have the state.

This is the code I’m using:

        cookies.encrypted[auth_response[:cookie].name] = {
          expires: auth_response[:cookie].expires,
          secure: true,
          http_only: true,
          same_site: :none, # I tried this but didnt work
          value: auth_response[:cookie].value
        }

Anything else i’m missing?

p.d.: I just followed the ruby template app.
