filesystemwatcher and invoke-restmethod

Can anyone advise why invoke-restmethod would not return error information when run within the -action {} block of a filesystemwatcher?

I’ve tried using specific error variables and error actions, but I cannot get it to generate anything.

To be more specific, when invoke-restmethod is called outside the filesystemwatcher -action {} block, I get the following error (which is what I want to see)

Invoke-RestMethod : Cannot create record.Invalid term for this field.00.000000
At line:1 char:1

  • Invoke-RestMethod -uri "
  •   + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
      + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand


…but inside the action script block, I get nothing.

I am not interested in why I’m getting the error, only that I should get an error when there is a problem with the call.
