Error when sending a file of type (document) Python telebot module, what to do?

Question

Python

Why is the file I am sending (book in fb2 format) not being sent?
And it gives an error that the variable in which I wrote this file is empty

import telebot

TOKEN = '---'
bot = telebot.TeleBot(TOKEN)

f = open(r"C:\Users\Beko\Desktop\Новая папка\Как изобрести все!.fb2","rb")

bot.send_document(мой id,f )

f.close()

bot.polling()

Error below:
telebot.apihelper.ApiTelegramException: A request to the Telegram API was unsuccessful. Error code: 400. Description: Bad Request: file must be non-empty <-(especially this moment please )

Answer 1

So he does not see the file, place the file in the folder with the bot and indicate the absolute path to it.
