When I go to do this, I'm getting an error from having a promise. This is my first time touching Typescript, I'm normally a Ruby/Elixir developer.

Diagnostics:
  pulumi:pulumi:Stack (exampleapp-dev):
    error: Running program '/Users/ben/Repos/exampleapp/pulumi/index.ts' failed with an unhandled exception:
    TSError: ⨯ Unable to compile TypeScript:
