Vercel: Zeit Now CLI `now dev` hangs

[davidbillamboz]

Hi,

I setup a demo project here.

The command now dev --debug run correctly, but when I request the url, the builder seems to be stuck and no error is shown.

Hey there @davidbillamboz. Sorry for the late reply. Are you still having this issue? Your example repo works correctly for me when I try it:

Node version: v12.15.0
Now CLI version: v17.1.2-canary.6
