2.3.0/gems/twitter-6.1.0/lib/twitter/rest/response/raise_error.rb:13:in `on_complete': Bad Authentication data. (Twitter::Error::BadRequest)

Simply put, I'm attempting to post a tweet using these pieces of ruby code:

require 'Twitter'

client = Twitter::REST::Client.new do |config|
config.consumer_key        = "my_key"
config.consumer_secret     = "my_secret_key"
config.access_token        = "my_token"
config.access_token_secret = "my_secret_token"
end

client.update("I'm tweeting with a @gem!")

I'm using 64-bit ruby 2.3.0 with the appropriate 64-bit dev kit on Windows 10.

However, a `on_complete': Bad Authentication data. (Twitter::Error::BadRequest) appears like so:
