Failed to load resource. Server Connect in Desktop app that's connecting to Data API (Server project) is not returning data. If I go directly to the URL for the API in the browser (e.g. http://localhost:8100/api/getUser) I can see the data.
Guesing this is a CORS issue? I do not recall this being mentioned in the documentation that walks through setting this up (Data API project and Desktop app project).
If you are going to access a server connect actions from a different project or mobile app you need to enable CORS in the global settings of the server connect in the project where the server connect actions are in.
