Reporting an Issue or Missing Feature

Reporting an Error. This issue started today after using the latest MSI from GitHub to update existing module (also installed via MSI). Process has worked flawlessly until the update.

Expected behavior

A new PnP site would be created in the target SharePoint Online tenant

Actual behavior

After successfully connecting to the SPO service and the PnPOnline service, attempting to execute New-PnPSite throws a fatal error and no site is provisioned.

Steps to reproduce behavior

Basic process is thus:

$SPOService = Connect-SPOService -Url [admin url] -Credential [admin creds]
$PNPConnection = Connect-PnPOnline -Url [spo root] -ReturnConnection -SPOManagementShell
New-PnPSite -Type TeamSite -Title 'My Site Title' -Alias 'MySiteTitle' -Description 'MySiteDescription' -Connection $PNPConnection
New-PnPSite : Could not load file or assembly 'System.Net.Http, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

@etherjack Works fine here on the latest version using Install-Module. Don't have the ability to try out the MSI at the moment. Are you able to give it a try by uninstalling the MSI and then running Install-Module SharePointPnPPowerShellOnline on your machine to see if it works after doing this?

I am running PS v4 and have had limited success using the PowershellGet module cmdlets. I'll give it another go.

Getting an error now indicating an issue finding the latest version. Should I specify a version explicitly?

Not sure what's going on there. Seems like a connection issue. I've started a VM and installed the MSI and am able to reproduce the error you're seeing using the MSI. I'll flag it to have a look at it with Erwin next Friday. The issue does not exist in the Install-Module version.

Thanks for reporting this @etherjack ! We've found the cause and it will be fixed in the June release which is expected to happen on June 9th, 2020.
