Azure Guest Configuration + Powershell DSC ERROR!!!

I found this guide online on how to publish local user accounts to Servers using Azure Guest Configuration and Azure Policy.  https://cloudbrothers.info/azure-persistence-azure-policy-guest-configuration/

i followed his guide, it worked fine.

However, i want to enable WindowsFeatures, and install msi packages, not just local user management.

So i followed the same steps, but i used his example for installing "Web-Server" instead.

I start to remediate the policy and this is the error i get. (also posted a screenshot in this thread)

Full Error
