Insecure Proxy Behavior with Invoke-(RestMethod|WebRequest) on 7.4.0-preview2 #19461
Description
Prerequisites

- Make sure you are able to repro it on the latest released version
- Search the existing issues.
- Refer to the FAQ.
- Refer to Differences between Windows PowerShell 5.1 and PowerShell.
Steps to reproduce
I use a number of script-based PWSH modules. In addition to using Invoke-RestMethod for a lot of API calls. These calls/modules are executed in a corporate environment with insecure/zero-trust proxies all over the place. The proxies cannot be avoided.
When testing PWSH v7.4.0-preview2, all script-based modules and IRM/IWR throw an error.
Eg. https://github.com/dell/OpenManage-PowerShell-Modules
I believe this is part of PR #18595. It seems that in certain scenarios, the change is breaking.
Adding the following to script-based modules and repos would be a large effort with external modules being out of my control. Unclear of best approach to mitigate in order to work before/after the 7.4.0 threshold.
if ($psVersionTable.PSVersion.Major -ge 7 -and $psVersionTable.PSVersion.Minor -ge 4) {
$querySplat.Add('AllowInsecureRedirect',$true)
}
Expected behavior
[2881.31]ms GitHub> # Works before 7.4.0-preview2
$querySplat = @{
Method = 'POST'
URI = $URI
Body = $bodyJSON
SkipCertificateCheck = $true
ContentType = 'application/json'
}
Invoke-RestMethod @querySplat
