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)
