.SYNOPSIS
|
||
|
|
Finds the last error in the errors stack that has a response stream and reads the value.
|
||
|
|
Obviously this only works for open/current sessions, as this is an in memory variable that can be wiped at any time.

|

|
|
.PARAMETER All
|
||
|
|
[switch] Finds all errors and writes them out serially from most recent to last
