can we change

if (($MyInvocation | Get-Member -Name 'Statement') -and $MyInvocation.Statement) {

to

if ($MyInvocation | Get-Member -Name 'Statement') {

---

Otherwise, this PR looks good to me @wraithgar @mbtools

Don't know how many people will run into this issue but it is in NodeJS 22.18.0+ / 24.3.0+
Appreciate the fix since this was my code that didn't account for this

I think we should keep both. The first checks that the Statement member even exists (which it does only on PowerShell 7+), the second condition checks if it has a value. If strict mode is off, if ($MyInvocation.Statement) does both for you, but with strict mode on, you're responsible to check that members exist. But they are checking slightly different things.

@splatteredbits Ok I understand the difference now
