Get-TroubleShootingPack not generating answers

Hi All

I can't find any information on this error and I am not sure what the root cause is

The command I am running is to generate an answer file for the Windows Update diagnostic tool is

Get-TroubleshootingPack C:\Windows\Diagnostics\system\WindowsUpdate -AnswerFile c:\temp\WUDAnswers.xml

Now i get prompted with the following

Please answer the following questions 
You will be asked a series of questions from the specified package.  The answers you provide will be stored in an answer file that you can use to automate question responses during package execution

Press enter to continue

As soon as i hit enter to continue the script exits and generates an empty answer file. Why am i not getting prompted to provide answers to the diagnostic tool and create a answer file that isn't empty?
