Fiori App Deployed to Cloud Foundry Showing "The redirect_uri has an invalid domain."

[Reinhardt]

Hi Experts,

I created an MTA project with a fiori app inside (On BAS). I have deployed it to my Cloud Foundry in BTP. However, I am seeing this when launching the app:

Here's the project structure

I've attached the code for xs-app.json and mta.yaml.

I believe I might need an xs-security.json file, specifying the callback URL, but if this is the case can I kindly get guidance on how to generate this file?

Much Appreciated,

Reinhardt
