Having trouble installing extensions only app

[aashby13]

Having trouble installing extensions only app. Dev went well and next step is to install on the client's store. The app consists of 2 extensions, a cart transform function extension and a ui extension. I'm under the impression that this qualifies as an app that does not need to be hosted. Please, let know if I am wrong on this. I end up with this screen (image attached) after using the custom distribution link. No installation happens.

The issue was missing scopes defined in the app TOML. Original version of the app had a Remix template, but it ended up we only developed extensions. I recreated the as an extensions only app and forgot to apply the scopes.

Hi Aashby13,

Great to hear you figured this out and thanks for coming back to post your solution.

When I ran npm run dev my app didn't install in the dev store and only pushed theme extension changes. When opening the preview I got 404.

I solved it by deleting 

unstable_newEmbeddedAuthStrategy: true, 

from the shopify config in shopify.server.js

After I did that, the app installed automatically. Theres an issue in shopify new OAUTH.
