I'm trying to get nodejs compatability running using these instructions - https://developers.cloudflare.com/workers/platform/nodejs-compatibility/#enable-nodejs-from-the-cloudflare-dashboard From what I can see I've done this, screenshot attached. However, as per second screenshot, when the code is building it's still giving me the error about nodejs compatability.

You can see in the docs page that you linked that only a (growing) subset of node APIs are available

OIh it's just that small list at the top?

For now, yes
