As of today, you can’t use `object` in the types of stack outputs. So, you have to declare the subnets output as strings:
```[Output("private_subnets")]
    public Output&lt;ImmutableArray&lt;string&gt;&gt; PrivateSubnets { get; set; }```
At the same time, you get an array of objects when you retrieve outputs from another stack, so you’d have to cast one to the other:
```this.PrivateSubnets = 
    vpcStack
        .RequireOutput("private_subnets")
        .Apply(o =&gt; 
            ((ImmutableArray&lt;object&gt;)o)
                .Select(o =&gt; (string)o)
                .ToImmutableArray());```

I realize this is confusing. Please file an issue on github if you have ideas how to improve this flow that would make sense for your use case.
