(RuntimeError) The tesla adapter has not been configured.

Hello

I tried to run the following example within the Phoenix project and got the following error: Example:

  @moduledoc false

  require Logger

  use Telegram.ChatBot

  @session_ttl 60 * 1_000

  @impl Telegram.ChatBot
  def init(_chat) do
    count_state = 0
    {:ok, count_state, @session_ttl}
  end

  @impl Telegram.ChatBot
  def handle_update(%{"message" => %{"chat" => %{"id" => chat_id}}}, token, count_state) do
    count_state = count_state + 1

    Telegram.Api.request(token, "sendMessage",
      chat_id: chat_id,
      text: "Hey! You sent me #{count_state} messages"
    )

    {:ok, count_state, @session_ttl}
  end

  def handle_update(update, _token, count_state) do
    Logger.info("Unknown update received: #{inspect(update)}")

    {:ok, count_state, @session_ttl}
  end
end

token = "6999904422:AAFueF9-djzcUgbt8XuV52qmeR9k-A5PIkk"

if token == nil do
  IO.puts(:stderr, "Please provide a BOT_TOKEN environment variable")
  System.halt(1)
end

{:ok, _} =
  Supervisor.start_link(
    [{Telegram.Poller, bots: [{CountChatBot, token: token, max_bot_concurrency: 1_000}]}],
    strategy: :one_for_one
  )

Process.sleep(:infinity)
