Getting request header dynamically using Javascript

[matheuskoiti]

Hello,

I'm trying to retrieve a value from a request header for using at body content section for my response. The request header the client sends looks like it:
Authorization: 123#abc

Then, at body content section at DuckRails, I tried to read that value this way:
var header = headers['Authorization'].split('#')[1];

But when I test the response I get a 200 Ok, but with this error:

Duckrails-Error: TypeError: Cannot read property 'split' of undefined

Am I reading the headers in a wrong way?
