Ruby NoMethodError // Telegram Bot - ruby

Question

I'm using this Ruby code for running Telegram messenger bot. After code is runned with /start command, it crashes with the following error:
./bot.rb:26:in `block (3 levels) in <main>': undefined method `[]' for nil:NilClass (NoMethodError)
from ./bot.rb:20:in `loop'
from ./bot.rb:20:in `block (2 levels) in <main>'
from /var/lib/gems/2.1.0/gems/telegram-bot-ruby-0.3.11/lib/telegram/bot/client.rb:41:in `block in fetch_updates'
from /var/lib/gems/2.1.0/gems/telegram-bot-ruby-0.3.11/lib/telegram/bot/client.rb:37:in `each'
from /var/lib/gems/2.1.0/gems/telegram-bot-ruby-0.3.11/lib/telegram/bot/client.rb:37:in `fetch_updates'
from /var/lib/gems/2.1.0/gems/telegram-bot-ruby-0.3.11/lib/telegram/bot/client.rb:29:in `listen'
from ./bot.rb:17:in `block in <main>'
from /var/lib/gems/2.1.0/gems/telegram-bot-ruby-0.3.11/lib/telegram/bot/client.rb:22:in `run'
from /var/lib/gems/2.1.0/gems/telegram-bot-ruby-0.3.11/lib/telegram/bot/client.rb:10:in `run'
from ./bot.rb:16:in `<main>'
Bot code is here:
require 'telegram/bot'
token = '...'
require 'net/http'
url = URI.parse('http://api.wotblitz.ru/wotb/clans/info/?application_id=...&clan_id=8')
req = Net::HTTP::Get.new(url.to_s)
res = Net::HTTP.start(url.host, url.port) {|http|
http.request(req)
}
require 'json'
str = JSON.parse(res.body)
ids = str["data"]["8"]["members_ids"]
n = 0
m = ids.size - 1
players = ''
Telegram::Bot::Client.run(token) do |bot|
bot.listen do |message|
case message.text
when '/start'
loop do
url = URI.parse('http://api.wotblitz.ru/wotb/account/info/?application_id=...&account_id=' + ids[n].to_s)
req = Net::HTTP::Get.new(url.to_s)
res = Net::HTTP.start(url.host, url.port) {|http| http.request(req)
}
str1 = JSON.parse(res.body)
nick = str1["data"][ids[n].to_s]["nickname"]
players = players + nick + "\n"
n += 1
break if n == m
end
bot.api.sendMessage(chat_id: message.chat.id, text:"#{players}")
end
end
end

If anyone is facing this same issue, I found a hacky fix for it. When running this code from my macOS terminal, I get the undefined method 'run' message. When I run it inside my vscode terminal on the other hand, it works correctly. I had this same issue on a Linux machine aswell. It probably has something to do with how my environment is setup.
Hope this helps someone out.
