undefined method `<<' for true:TrueClass

I have this strange error (for me) I can not figure out why is happening.

Sometimes when I call RestClient.get 'http://google.com' I got a response and some times I get this error undefined method '<<' for true:TrueClass

I am using Rails 4.1.8, Ruby 2.1.5p273 and RestClient 1.7.2

    2.1.5 :010 > RestClient.get 'https://google.com'

Solution

  • Your RestClient.log is set to true. Find where that happens by intercepting the setter:

    def RestClient.log=(value)
  raise "HERE!"
end

    then just wait till the exception is triggered, and see from the stack trace who assigns silly values. :)
