Delayed job error while making http requests

I am running into an error in utils.rb:333 when I process a job with delayed job that works perfectly when run synchronously. Basically what I am doing is making a get request in my code and when I do, I run into the error. This is the line of code that hits the error:

self.fb_friends = (JSON.parse self.fb_token.get('me/friends')).first[1] unless self.fb_friends

self is a ruby class and self.fb_token is created here

OAuth2::AccessToken.new client, fb_token_string

where client is the result of the call to OauthHelper::client and fb_token_string is a token string from facebook

here is my stack trace:

{You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.delete
