Hopefully this will adress the issues in PR #15491

I’m not sure why the build would fail — I hadn’t changed anything besides removing the CmdletBindingAttribute parameters…
I’ve checked if build.psm1 or ci.psm1 (which is where the errors semm to be happening) ever mention “WhatIf” or “ShouldProcess” — they don’t.

ci.psm1’s Invoke-CIBuild seems to be failing because Get-PSOptions (imported from build.psm1) returns $null.
However, this is because of a global variable set at the top of the script, which was there before my changes occurred.

I’m very confused.
