How to config this project?

[DarkHorseCorder]

I have tried to use this project but after install npm module and run server, I have this error when I trying to register.

I have project id and secret, so have tried to add them to request header for auth

But this is not correct one

How can I add project id and secret?

other tutorial says like this

But I can't use Buffer in this project because app.js is not node.js

Help me please
