Error: System.AggregateException: One or more errors occurred. (Value cannot be null. (Parameter context)) ---> System.ArgumentNullException: Value cannot be null. (Parameter context)

I am facing this issue whenever I try to use a list view/ Datagrid to show the feedbacks related to a specific focus area card. I have no idea on why this problem is happening and is preventing me from running the application. I am using Focus_Area_Card entity as a page parameter. I have provided two screenshots which is the error and the domain model. Thank you.

Are you using the page parameter in the listview?

You could try to add a dataview with the Focus Area Card object and nest the listview inside the dataview and see if this resolves the issue.
