Custom Application keeps showing the loading animation in the Merchant Center

[ravish-goel]

I am deploying the OOTB Custom Application starter template using vercel. When I try to preview the deployment using Vercel it keeps showing the loading animation with a message "This is taking longer than usual." In Merchant Center as well, the app is behaving in the same manner. Please help me here.
This is my app config:

This is my Merchant Center config:

Hi @ravish-goel

The env.production.url in the app config is wrong, you need to point it to the URL where your application is hosted, in your case https://masketavengers.vercel.app (the same as in the "Application URL" field in the UI form).

That should likely fix your issue (you would need to rebuild and redeploy the changes).

Let us know how it goes.
