Shopify_app: Uninstall app, re-install again redirects without oauth

[quocble]

I'm so stumped on this issue. I got rejected from the beta approval and really want to get this in. I appreciate anyone can help.

Steps to reproduce

1. Install app
2. Remove app
3. Install app again

Expected: Send to "Install app" prompt screen
Result: The default /login with the input box

If I re-install again, then it shows properly. It happens exactly once after the app is removed.

Gem: ShopApp 6.4.2

Logs

From the logs, you can clearly see the request shows shopify_domain, redirected, and the domain gets lost.

Sounds like a session issue. If you clear cookies in between does it work as expected?

[quocble]

Yes. How do suggest to fix this in the code? I believe I use standard boilerplate code..

[kevinhughes27]

Are you using the embedded app sdk? I am pretty sure thats just how it works. Let me follow up with the apps team.

I'm using embedded app sdk. Thanks. I was corresponding with Oren.

Hey Guys,

I had a similar issue on one of my apps, and the fix was to make sure the link to your app in the Partner Dashboard is pointing at your /login url of the app.

Sounds like the ?shop= param is not being passed along on the redirect.

Would be great to know the ultimate cause, but at least this can be used as a workaround.

Ps. I'm not a Shopify employee, just another app developer ;)

[kevinhughes27]

We're looking into it! I want approval to be smooth if you use ShopifyApp.
