*You don't have this app installed* after deleting partner app, re-authing on Shopify, and trying anything else

[cyrilchapon]

(Just filing an issue and instantly closing it, in order to document a strange behavior I encountered, because I've been stuck on this for almost 5 days without finding anything. I've been unlocked thanks to a question on partner discord).

Context

After

• creating a new app with the template (on the API 6 branch, or any other derived branch)
• deleting the app be it on the partner UI or with --reset,

I got stuck in a strange "loop" (that's not a redirect loop in the strict sense of it), like so :

The trouble

• Running yarn dev
• Clicking on the shareable link
• The app flashing it's UX on a standalone page
• The almost instantly redirecting to Shopify (this is intended, to display the app in the iframe, this is not the root of the bug)
• After this, instead of showing the app frontend, Shopify shows a screen saying

  You don't have this app installed Get App name and try again [Install]

• Clicking on "Install" will redirect twice and show the page again, leading to an infinite situation

The issue

This is due to the auth middleware thinking the app is installed; while it's not ! This line reports "true" for appInstalled, so never redirectToAuth (while it should); and later this line reports false; which causes the "install loop".

Why would appInstalled wrongly report true ? Because the sqlite database still contains your old, previous-app-bound installation !

Resolution

• Remove any .sqlite file from source code, and done

Thank you so much for pointing this out @cyrilchapon You may just have saved me for more countless hours of frustration.
