Internal server error running starter code

Trying this out for the first time and running into the following error in my console testing the server locally:

It looks like the edgeConfig might be missing - do I have to link the project with vercel before the server would work?

[matthewcheok]

I tried running vercel link which initially failed because of

Error: Invalid request: `files` should NOT have more than 15000 items,

I got around that by duplicating .gitignore to .vercelignore but it didn't solve the above issue.

[matthewcheok]

Ah nevermind, the file/line was incorrectly reported.
I copied the starter code which was failing...

let greeting = EdgeConfig.default.get("greeting").string!
