I think I'm missing something obvious. I have a Pulumi.yaml that defines a specific configuration parameter as being an array as documented here: https://www.pulumi.com/docs/intro/concepts/config/#strongly-typed-configuration However, when I try to fetch the value (typescript) there is a type mismatch that breaks hard:

let hostAnnotation: { [key: string]: string } = {};
  if (cfg.get("traefikHosts")) {
    hostAnnotation = {
      "somekey": (
        cfg.require("hosts") as unknown as string[]
      ).join(","),
    };
  }

I get:

TypeError: cfg.require(...).join

is not a function I cannot for the life of me work out how to make the type checker happy 😞

require

gives back a string. Use

requireObject

instead:

new Config().requireObject<string[]>('hosts')

nice! Thanks @steep-toddler-94095
