Investigate why running cmdlets result in this error. For example -> node .\test.js Get-Process <- causes this error. While this works -> node .\test.js 'Get-Process | Out-String'.

I can't even get test.js to run, but does outputs.Select(pso => pso.BaseObject).ToList() strip of all of the ScriptProperties normally returned with Get-Process?

[dfinke]

what error do you get?

Thanks for posting. I know nodejs got upgraded and edge had some fixes. May need to pull them over.

[cdhunt]

FYI: tried on another machine with Node 0.8.14 and received the same error.I must be missing something.

[dfinke]

you need to set the $env:EDGE... variable. check the Invoke-PSNode.ps1

also are you running it from the tryPowerShell dir?
using
c:> node test.js

[dfinke]

Chris, found the issue, here's the write up #7 (comment)

[cdhunt]

Thanks. I got everything running and stepped through the code. I have no ideas other than replacing JSON serialization in Edge with Json.Net which has worked well with PSObjects for me in the past.

[dfinke]

Terrific. I saw some info just the other day about folks switching to Json.Net. It was on my list.

Looking forward to playing with it.

Thanks
Doug
