How would I make my Python Discord bot mimic all messages sent?

Question

I am writing a Discord bot using Python (v. 3.6.1). One of its functions detects all messages sent in a channel, processes them, and then responds to the messages in said channel. (At least, that's what I want it to do.)

I have tried this:

@bot.event
async def on_message(message):
    await bot.say(message.content)

The function responds when a message is sent, but not in the way that I want it to. I instead get an error:

discord.errors.InvalidArgument: Destination must be Channel, PrivateChannel, User, or Object. Received NoneType

How would I fix this? Many thanks!

Please include the code that is giving you trouble. The error message alone is rather useless. See How do I ask a good question? — Galen

You cannot use bot.say outside of a command.

Can I use bot.say in other places aside from commands?

No. They only work inside commands due to the way the magic involved works.

To have the bot repeat every message sent, you can use send_message. Below is an example.

@client.event
async def on_message(message):
    await client.send_message(message.channel, message.content)
