Perhaps a console.log is not executing at the right stage. I have this:

let myStackName = myStack.outputs.apply(o => o["VpcId"]);
console.log("out:", myStackName);

which prints this in Diagnostics after running `pulumi update`:

pulumi:pulumi:Stack: infrastructure-infra-dev
    info: out: Output {
      __pulumiOutput: true,
      isKnown: Promise { <pending> },
      resources: [Function],
      promise: [Function],
      apply: [Function],
      get: [Function] }
