Trying to write a simple PowerShell script, but got stuck with an error, and I can't find any solution on the web.

$stream = [IO.MemoryStream]::new([Text.Encoding]::UTF8.GetBytes('aaaaaaaaaa!'))
Get-FileHash -InputStream $stream -Algorithm SHA512
AddPnPFile -Path './bundle.json' -Folder "$($FolderRelativeURLGeneral)$($folder)" -Stream $stream

Why am I getting an error for providing a stream to the Stream parameter? Removing the parameter solved the issue, but obviously I want to write something to the file, so can someone tell me how to write content to the file? Do I need to create a filestream out of the stream? However, the documentation doesn't specify that it has to be a file stream. How come it doesn't work?

How to convert a string to a stream object in Powershell?

  • what is the exact error? PoSh errors usually have a good deal of useful info ... [grin] add it to your Question, not in the comments ... and please use code formatting so it will be easily readable. Commented Mar 9, 2020 at 20:35

In PowerShell, a parameter set specifies which parameters can be used together when calling a function.

You can use parameters from one set or another set, you cannot mix and match.

Checking the documentation for Add-PnPFile, Path and Folder are part of one parameter set, while Folder and Stream are part of another; there is no parameter set that has all 3 parameters.

I think you're looking for FileName (which i assume creates a file from the stream) instead of Path (which is a local file path).
