Connect to Squarespace Server

Hi.

I can't connect to squarespace-server. I've got this error: 

What is supposed to have in .squarespace-local-developer, on my global folder? This file is returning an empty object.

And my localhost return a 500 from GET.

{"code":500,"message":"There was an error processing your request. It has been logged (ID e1a7cfe94d287020)."}

Anyone else?

Thanks.

I figured out what the error means. 
You need to take out the "s" from security on http.
