"RequestError: Error: connect ECONNREFUSED" on New Project

[MarekOCLC]

• On Mac zsh, using nvm, node version 16.14.2 (LTS), on a freshly cloned aem-guides-wknd
• I followed the aemfed README to use it via package.json
• When I run npm run aemfed this is the output:

➜  aem-guides-wknd git:(main) ✗ npm run aemfed

> aemfed
> aemfed -t "http://admin:admin@localhost:4502" -w "ui.apps/src/main/content/jcr_root/"

I also tried with node 6.17 LTS as noted in the README but ran into an error that seemed to say I needed to update node.

Any help would be much appreciated! Thank you!
