HoloLens 2 ObjectDetectionManager saying "No Connection to Database"

For custom vision what do I put in the ObjectDetectionManager and where can I find it?

I am following: https://docs.microsoft.com/en-us/le...ials/7-exercise-integrate-azure-custom-vision/

however, I keep getting the error stating "No connection to Database" despite there being no mention of needing a database Web Hosting

 

I have the same problem, does anyone know how to help?
