Discord bot not working on Heroku (?

Question

Python

If you run the bot on a PC, it works, but on Heroku it refuses in every possible way.
The github repository has the following files:

• Procfile
  
• README.md
  
• disbot.py
  
• requirements.txt
  
• runtime.txt
  

Procfile
worker: python disbot.py
disbot.py

import discord
from discord.ext import commands
from discord.ext.commands import Bot

Bot = commands.Bot(command_prefix='!')

@Bot.event
async def on_ready():
    print('Бот онлайн!')

@Bot.command(pass_context = True)
async def hello(ctx):
    await Bot.say("Hello!!!")

Bot.run("")  // токен убрал на всякий случай

requirements.txt

discord.py
aiohttp
websockets
chardet

runtime.txt
python-3.6.8

Answer 1

When you wrote discord.py in requirements.txt, you have the latest version of discord.py installed. Bot.say ("something") refers to the old version ( async ) in the new one ( rewrite ) you need to write ctx.send("something")
