Get-MgUser imports an alternate version of Microsoft.Graph.Authentication, causing AggregateException error

[Lauwnch]

Hello,

Working with a fresh install of Microsoft.Graph from PSGallery. After Connect-MgGraph, Microsoft.Graph.Authentication version 1.25.0 is imported. Then, once Get-MgUser is run, Microsoft.Graph.Authentication version 1.27.0 is imported. Per past issues on this project where AggregateException occurred, this version mismatch may be responsible, but not sure how to resolve on my end since the module is responsible for these imports.

Only thing that you don't see in the snippet below is that, in a previous powershell session, I did run Select-MgProfile -Name "beta".

Any help is appreciated!

Thanks for following up on this.

The error is due to different versions of the modules being auto loaded by PowerShell in your session. You'll need to restart your PowerShell session either before or after running Update-Module Microsoft.Graph.

Only thing that you don't see in the snippet below is that, in a previous powershell session, I did run Select-MgProfile -Name "beta".

Running Select-MgProfile -Name "beta" auto imports Microsoft.Graph.Authentication v1.25.0. Update-Module Microsoft.Graph updates the locally installed modules to v1.27.0. Running Get-MgUser -All after the update means you are importing the latest version of Microsoft.Graph.Users (v1.27.0), which auto-imports Microsoft.Graph.Authentication v1.27.0 hence the error.

PowerShell does not unload imported modules when you update them. You'll need to restart the PowerShell session to use the newly updated modules.

Thanks for the response @peombwa.

Restarted computer, fresh powershell session, issue persists:

@Lauwnch, your repro steps shows Microsoft.Graph.Authentication v1.25.0 wrongly being auto loaded by PowerShell despite having v127.0 installed. This could be due to two issues:

• PowerShell is wrongly importing an older version as part of its auto load feature. For this, you'll need to uninstall the older version of the module and do a fresh install. See https://learn.microsoft.com/en-us/powershell/microsoftgraph/installation?view=graph-powershell-1.0#uninstalling-the-sdk for more details. Alternatively, you can upgrade to the latest version of PowerShell at https://aka.ms/PSWindows.
• Something is wrong with how the conflicting modules are installed on your machine.

I can't repro this behavior in PowerShell 5.1 despite having both v1.25.0 and v1.27.0 of the modules installed on my machine.

Could you share the output of the following to right after the error message:

Get-Module Microsoft.Graph.Users, Microsoft.Graph.Authentication -ListAvailable | Select Name, Version, ModuleBase

[Lauwnch]

@peombwa Thanks especially for that final tip - checking the ModuleBase of both versions of Microsoft.Graph.Authentication untangled the mystery.

On my previous work computer, Microsoft.Graph (v1.25.0) was installed in my \Documents\WindowsPowershell\Modules. OneDrive must have sync'd that location, and brought that folder over to this new machine.

On the new machine, when I installed Microsoft.Graph (v1.27.0), it installed to Program Files\WindowsPowershell\Modules.

My PSModulePath lists the user profile location first, so it pulls the Connect-MgGraph from there, loading v1.25.0 of Microsoft.Graph.Authentication. Then when I call Get-MgUser, it uses the Program Files version (v1.27.0) since Microsoft.Graph.Users isn't present in my user profile module location.

Resolved by uninstalling the module, deleting the graph modules out of my user profile location, and re-installing the module.

Thanks again!
