#generic Invoke-RestMethod / WebRequest error handler

#https://stackoverflow.com/questions/39319680/onelogin-rest-api-with-powershells-invoke-restmethod

function Failure {

$global:helpme = $body

$global:helpmoref = $moref

$global:result = $_.Exception.Response.GetResponseStream()

$global:reader = New-Object System.IO.StreamReader($global:result)

$global:responseBody = $global:reader.ReadToEnd();

Write-Host -BackgroundColor:Black -ForegroundColor:Red "Status: A system exception was caught."

Write-Host -BackgroundColor:Black -ForegroundColor:Red $global:responsebody

Write-Host -BackgroundColor:Black -ForegroundColor:Red "The request body has been saved to `$global:helpme"

break

}

Then, wrap all of your Invoke-RestMethod calls in a try Catch block like this.
