extend Invoke-MgGraphRequest to handle PUT body / Unauthorized during build

[KaiWalter]

I need to PUT a body with this operation https://graph.microsoft.com/beta/identityGovernance/entitlementManagement/accessPackageAssignmentPolicies/{id} and get a 400 Bad Request although the same body works on the respective Graph API operation.

If I interpret InvokeMgGraphRequest.cs correctly, the body is just not added to the request stream for a PUT method operation.

I wanted to extend the CmdLet myself but already struggle with
.\tools\GenerateAuthenticationModule.ps1 -Build

which gives me an authentication error

currently I use this workaround

        $client = [Microsoft.Graph.PowerShell.Authentication.Helpers.HttpHelpers]::GetGraphHttpClient()
        $stringcontent = New-Object System.Net.Http.StringContent(($body | ConvertTo-Json -Depth 15), [System.Text.Encoding]::UTF8, "application/json")
        return $client.PutAsync($uri, $stringcontent).GetAwaiter().GetResult()

instead of

return Invoke-MgGraphRequest -Uri $uri -Method Put -Body $body

@KaiWalter We have fixed the issue you noted. The bad request was caused by Invoke-GraphRequest sending the wrong Content-Type header text/plain instead of application/json for PUT requests when -ContentType parameter is not set.
A fix will be released with the next version.

In the mean while a workaround would be to specify the -ContentType explicitly.
Invoke-MgGraphRequest -Uri $uri -Method Put -Body $body -ContentType application/json

To fix the unauthorized issue during build, remove the following lines from Nuget.config. They point to our internal build feed, we will correct this as well in the next build.

thanks @finsharp - adding -ContentType "application/json" worked - I will try nuget feed next

[KaiWalter]

removing lines from Nuget.config worked
