Queries Related To Shopify App Submission

[RCJ]

Can anyone guide this, we received mail while we submit the app for review. 

Your app must be a finished and complete product in a stable state, free from any incomplete functionality and/or bugs. See for additional details, after installing the app we encounter an error in the app's UI, nothing happens after opening the app from the App index.

Issue Report: After installing the app from the Shopify App Store, users are encountering a blank page with no apparent functionality. We acknowledge the presence of this UI error and are dedicated to resolving it promptly. we are not aware of what we need to show in the page.

It will be helpful if we have a step-by-step guidance.

Hi RCJ,

Is the auth flow working as expected - as in the merchant can install the app correctly? What is your intended action once this happens - should there be an onboarding flow to set up the app, or simply the merchant lands on the app UI/ dashboard?

Hi Liam,

Thanks for your response.

Once our customer installs RC Jewelry Dropship app. At the backend, we will get auth code from the endpoint then we will exchange our auth code with shopify to get the access token then it will be redirect to our RCJ platform UI Connect My Store

[Liam]

So is the problem here that the redirect is not working and the merchant stays on the Shopify admin?

[RCJ]

After installation, its redirecting correctly to the RCJ UI. But when the merchant check from the shopify store, RCJ app remains blank while open app.
So, we need to show the RCJ UI through endpoint, if so where we need to insert the endpoint in shopify partner app? Apart from this we need to do any manual changes in the shopify partner app?

Hi RCJ,

One option to ensure redirects are operating correctly could be to use the App Bridge Navigation API that allows your app to navigate to external URL in same window (there's also more info on that from the MDN web docs). 

You'll also want to ensure that the app's authentication flow works correctly. When a merchant accesses the app from their Shopify admin, the app should authenticate the merchant and establish a valid session. Use OAuth for authentication, and verify the merchant's credentials before displaying the UI.

If the redirection and authentication are set correctly, but the page remains blank, there might be JavaScript errors or network issues. You should check the browser's developer console for any JavaScript errors and inspect network requests to ensure they are not failing. Sometimes, issues like Cross-Origin Resource Sharing (CORS) can lead to problems in loading the app's UI.

Hope this helps,
