Deployed App and Invalid oAuth Redirect URL

[karmatrade]

Hi there! I am following the instructions here: to deploy an app using Fly.io and Shopify app bridge.

I've gone through the instructions 3-4 times. It seems my OAuth Callback URL is still incorrect:

Oauth error invalid_request: The redirect_uri is not whitelisted

The redirect url is:

https://karmatradeteststore.myshopify.com/admin/oauth/authorize?client_id=4956ed015365002afcbd583ade...

which decodes to:

https://karmatradeteststore.myshopify.com/admin/oauth/authorize?client_id=4956ed015365002afcbd583ade...

I've attached my fly.toml, useAuthenticatedFetch.js files.

(removed api key and secret for security purposes)

I've also checked by Fly secrets to make sure it has the right url.

Now, it seems to be the correct url, but it still doesn't want to go through?
