Migrating a web app from .NET Core 2.2 => .NET Core 3.1 and seeing this error when running CompileRenderAsync.

The project does not make use of DI to instantiate the engine, it uses the following code instead:

var type = model.GetType().Assembly.GetType("Nkr.Model.Root");

var engine = new RazorLightEngineBuilder()
                .UseEmbeddedResourcesProject(type)
                .SetOperatingAssembly(assembly)
                .UseMemoryCachingProvider()
                .Build();

var resultTask = engine.CompileRenderAsync(resourceName, model);
return resultTask.Result;

Is it required to use DI to instantiate the engine?

Am I missing something in the above code?

This seems to be something on my end..
