Don't work by following the readme

[cybertouchllc]

Note: Creating a sapper project from the Dashboard and 0 config, works great, but I think that I cannot make authenticated apps with that approach since that template do sapper export instead of sapper build.

Don't know if that the main reason of the existence of this builder, or if it has more advantages to the one available as a template on Vercel.

I followed the readme and didn't worked, I get this in the logs:

I just tried it and it works fine. Did you ignore the __sapper__ folder?
