python - AttributeError: 'Client' object has no attribute 'send_message' (Discord Bot)

Question

For some reason send_message isn't working properly on my Discord bot and I can't find anyway to fix it.

import asyncio
import discord

client = discord.Client()

@client.async_event
async def on_message(message):
    author = message.author
   if message.content.startswith('!test'):
        print('on_message !test')
        await test(author, message)
async def test(author, message):
    print('in test function')
    await client.send_message(message.channel, 'Hi %s, i heard you.' % author)
client.run("key")

on_message !test
in test function
Ignoring exception in on_message
Traceback (most recent call last):

You are probably running the rewrite version of discord.py, since the discord.Client object does not a have a send_message method.

To fix your problem you can just have it as:

async def test(author, message):
    await message.channel.send('I heard you! {0.name}'.format(author))

but for what i see you doing I reccomend using the commands extension

This makes creating a bot and commands for the bot much simpler, for example here is some code that does exactly the same as yours

from discord.ext import commands

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

@bot.command()
async def test(ctx):
    await ctx.send('I heard you! {0}'.format(ctx.author))

bot.run('token')
