Hi,

We are seeing a weird issue with screen flow using TreeNavigation7 harness. During the initial case journey the screen renders with error messages when validation rules executes. However after saving the case for a while and come back this default behavior is not working. We simply see a grey screen on the portal. 

Behind the scenes validation rule is setting error message, but on the harness it is failing to render the whole screen. But when we correct the data and proceed case moves to next screen in the screen flow. 

We noticed a java script error in the browser console. Also for the first time there is no error in the console.

Same works fine with tabbed harness. We are using the ootb harness for TreeNavigation7, no customization. Any idea on this exception please? Appreciate your help!
