[FIXED] Discord.py : line 343, in _run_event await coro(*args, **kwargs) TypeError: on_message_edit() takes 1 positional argument, but 2 were given

Issue

I'm running a script, it shows me this error message:

Ignoring exception in on_message_edit
Traceback (most recent call last):
  File "C:\Users\Debashis\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\client.py", line 343, in _run_event
    await coro(*args, **kwargs)
TypeError: on_message_edit() takes 1 positional argument but 2 were given

but my code is nothing more than:

@bot.event
async def on_message_edit(message):
  pass

I'll be working on the function later, but it gives me an error already (message intents are enabled). The other posts I found on this topic didn't help me at all. I don't know if that'll be helpful, but I'm not using discord.Client. I'm using discord.ext.commands.Bot.

Solution

It should be:

async def on_message_edit(before, after):

Where before is the previous version of the message and after is the current version (documentation).

You might also think about using on_raw_message_edit as it's not relying on an internal cache (documentation).

async def on_raw_message_edit(payload)
