why am i getting “undefined method `strip' for nil:NilClass” when i'm not calling the strip method?

Question

I'm building a rudimentary app using the Twilio API, and have reached a block when using figaro to store account_sid and auth_token as environment variables in application.yml.

In my controller I have:

require 'twilio-ruby'
require 'figaro'
class TwilioController < ApplicationController

def voice   
account_sid = ENV["TWILIO_ACCOUNT_SID"]
auth_token = ENV["TWILIO_AUTH_TOKEN"]
@client = Twilio::REST::Client.new account_sid, auth_token

message = @client.account.sms.messages.create(:body => "Hello",
:to => "+12345678",
:from => "+12345678")
puts message.sid
end
end 

And in config/application.yml I have:

# TWILIO_ACCOUNT_SID: 1234567890
# TWILIO_AUTH_TOKEN: 1234567890

The program works as intended when I replace the env variables with actual values, so the most I'm able to grasp at the moment is that something is preventing those variables from being set.

Answer 1

I just upgraded from Rails 4.2 to Rails 5 and started getting this error.

For me, it was because a newer HAML version was no longer tolerant of a pre-existing empty javascript block.

:javascript

I deleted the ':javascript' line and everything was fine afterwards.

Answer 2

move constants to development.rb

and then just:

account_sid = TWILIO_ACCOUNT_SID
