7.4.0 Breaking change: Passing -OutFile $null to Invoke-WebRequest fails #20744

@nowakca

Description

@nowakca

Prerequisites

Steps to reproduce

Minimal version

Invoke-WebRequest "http://www.microsoft.com" -OutFile $null

Version that is more closely related to how that sneaks in as a surprise script breaker

function DoTheThing($file) {
  $Params=@{
    Uri="http://www.microsoft.com"
    OutFile=$file
    }
  Invoke-WebRequest @Params
}

DoTheThing

Expected behavior

Should return the results of the web call to the output stream

Actual behavior

Invoke-WebRequest: Cannot validate argument on parameter 'OutFile'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

(Works correctly in 7.2.17 and 7.3.3)

No really necessary, literally just paste Invoke-WebRequest "http://www.microsoft.com" -OutFile $null into a shell and watch the error show up
