Your config parameters token and secret appear to be insecure!
This is **VERY** insecure, as these values serve as authentication tokens for
internal APIs and session cookies. You **must** change these values in order to
prevent potential exploits.

To generate new values for these parameters, you can use the following command:
    node -e "console.log(require('crypto').randomBytes(64).toString('base64'))"

Exiting here, as the security of your application cannot be guaranteed...
