How could we get the ErrorStatus which holds a Response?

Hello,

We wonder how could we get the following attribute:

Which is found in the response Header being sent from a Operation to a Process, when there is an exeptionWwe would need to access the Response ErrorStatus text in the Process

We have already tried:

$$$LOGINFO("..%Process.%PrimaryRequestHeader.ErrorStatus: "_..%Process.%PrimaryRequestHeader.ErrorStatus) //It shows "1"

$$$LOGINFO("$System.Status.GetErrorText(..%Process.%PrimaryRequestHeader.ErrorStatus): "_$System.Status.GetErrorText(..%Process.%PrimaryRequestHeader.ErrorStatus))  //It shows an empty string
