404 Not found while executing client.expand

[luilver]

Following the README when I try to client.expand I get a 404.

This is my code:

require 'bitly'
token = '«myTokenHere»'
client = Bitly::API::Client.new(token: token)
bitlink = client.expand(bitlink: "https://bit.ly/«myShortCode»")
p bitlink.long_url

This is my env:

$ ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]

$ gem list | grep bitly
bitly (2.0.1)

This is the pry-ed output ( :

$ ruby bitly.rb

I found the problem is the included protocol within bitlink. Removing https:// fixed it.
