Hi. I'm trying to write some unit tests for a stack that includes a couple of `StackReference`  objects with public properties that use `RequireOutput` but I'm having no luck. I've followed the setup here: <https://github.com/pulumi/examples/tree/master/testing-unit-cs> and I've inspected the JSON configuration I'm setting for the `PULUMI_CONFIG` environment variable, but keep getting a null ref exception when trying to access any of these stack reference values :disappointed: anyone come across something similar?

FYI on the exception:
```Pulumi.RunException: failed with an unhandled exception:
System.NullReferenceException: Object reference not set to an instance of an object.
   at Output&lt;object&gt; Pulumi.StackReference.RequireOutput(Input&lt;string&gt; name)+(ValueTuple&lt;string, string, ImmutableDictionary&lt;string, object&gt;&gt; v) =&gt; { }
