Can this be run locally without setting up an IAM instance?

I just tried setting this up on my local laptop, but when I run npm start it fails with the following error:

npm start

> [email protected] start /Users/brian.tully/Sites/perftools-runner
> node --experimental-modules server.mjs

(node:75810) ExperimentalWarning: The ESM module loader is experimental.

Can this be run without the serviceAccount.json and bitlyAccount.json or are these required no matter what?
