Bad request (400) after new install

[ranyefet]

OS: MacOS 10.12.1
Node: 6.4.0
Gatsby: 0.12.6

I just installed gatsby for the first time using npm i -g gatsby and created a new project using gatsby new website.
After installation, I ran gatsby develop my console looks fine (no errors):

Listening at: http://0.0.0.0:8000
webpack built 94d5d608d43bde0b78a2 in 4959ms

When I open my browser at http://localhost:8000 I get the following error:

{
  "statusCode": 400,
  "error": "Bad Request",
  "message": "Invalid cookie value"
}

I would love to try out Gatsby, Help is appreciated.

Apparently I had an old express cookie which cause the issue, deleting cookies fixed the issue.
