How to get Powershell Invoke-Restmethod to return body of http 500 code response

The other answer does get you the response, but you need an additional step to get the actual body of the response, not just the headers. Here is a snippet:

try {
        $result = Invoke-WebRequest ...
}
catch {
        $result = $_.Exception.Response.GetResponseStream()
        $reader = New-Object System.IO.StreamReader($result)
        $reader.BaseStream.Position = 0
        $reader.DiscardBufferedData()
        $responseBody = $reader.ReadToEnd();
}
