Sorry for missing the previous couple of asks on this. If you have not yet checked out https://pulumi.io/reference/programming-model.html#outputs I'd suggest taking a look at that - it covers many aspects of how to work with `Output`s. As for invoking

exec

- you'd need something like:

output.apply(v => {
  exec(v);
});

That is - you only have access to the value of the output within the callback for the

apply

, so you'll want to invoke the

exec

inside that scope. This is because the

apply

will actually not always run - it will only run once the value of the output is known - which may not be available during a preview. (In the case of StackReference though, I believe it is the case these will always be available).

I see, I'll try that. Thanks!
