Attempted to perform an unauthorized operation.

Hi @JustinGrote ,

Thank you for a great manual!

I've been toying around with Azure Functions and Powershell. I've come as far as to install nuget and trying to install modules, which actually produced no error, but also no result. The I stumbled opun your Missing Manual. I tried save the module instrad of installing it, and got this error instead:

Are you still able to install modules like that?

Start by reviewing the reported Azure Functions module-install flow, including NuGet, PowerShellGet, and the Save Package operation, and try to reproduce the unauthorized-operation message. Confirm whether module installation is still supported and document the current behavior or a reproducible cause for the failure.
