Creating an Event/Hit Attribute from RealitTea Viewer (RTV) or Browser-based Replay (BBR) redirects to an error page: "An error has occurred. Pleas

The typical cause of this error is that the .NET framework 4 is assigned to the DefaultAppPool that runs the Tealeaf application.? .NET 4 has validation rules for the query strings.? A sample error from the Application log is shown below:

Exception information:
Exception type: HttpRequestValidationException
Exception message: A potentially dangerous Request.QueryString value was detected from the client (rspselection="<test").

The application pool for Tealeaf runs under the .NET 2 framework. Change the assignation from .NET 4 to .NET 2.
