I am getting this error in the Build and Deploy job phase of an Azure Static Web Apps CI/CD check-in. The first part of the error message is: 

Microsoft (R) Build Engine version 16.8.3+39993bd9d for .NET

It appears that all project nuget dependencies are throwing similar messages. My Nuget Package Manager has both Allow Nuget to download missing packages AND Automatic check for missing packages during build in Visual Studio Checked.

Does anyone know what is causing this and how to resolve?

    Hi, @Leonard Kong .

    There have been cases in the past with similar issues with security updates to .NET SDK versions.
    Updating the SDK was the solution then.

    I can't say for sure since I don't have a full view of your project, but it's worth a try.
