discord.py error when forwarding embeds to another channel

Question

I have an issue about discord.py. I have a code for forwarding embed messages to another discord channel, but it gives me an error. How can I solve it?

Error:

Ignoring exception in on_message

import discord
from discord import channel

async def on_ready():
    print("Bot is ready")

Edit 1: sent message is "@deleted role"

async def on_ready(): print("Bot is ready")

class MyClient(discord.Client):

Answer 1

Have you checked what the value of the variable message.embeds[0] is? If message.embeds[0] is None (NoneType), then it is very possible that it is the reasoning behind your issue. Note these things:

1. If you are sending an embed, you do NOT need to send a message
2. When you do send an embed you need AT LEAST a title OR a description. That is the ABSELOUTE MINIMUM.

Try see the value of message.embeds[0]. Also, I noticed something as I was doing testing for you.

You can see that the first object is from await channel.send(embed=embed), but the second one is from await channel.send(message.embeds[0]). Have you tried manually adding the arguments of the discord.Embed object to another embed? Like:

await channel.send(
    embed = discord.Embed(
        title = message.embeds[0].title,
        description = message.embeds[0].description,
        # etc.
    )
)

Answer 2

The "Cannot send an empty message" error happens because the bot tries to send a message with empty content and no embed (presumably because there was a message in the source channel that had neither, e.g. a message with just an image - those go to message.attachments, not to message.content)

---

The easiest way to get around this is to simply try: ... except your await channeltosend.send(message.content, embed=message.embeds[0]) call and ignore/log the error, but you may want to copy any attachments to the target channel anyways, so perhaps you should check for attachments and copy them over instead. You can achieve that by using to_file() on the attachment and then submit that to the file-parameter of channeltosend.send (or files and a list of attachments if there are multiple) something like:

files = [await attachment.to_file() for attachment in message.attachments]
...
await channeltosend.send(message.content, embed=message.embeds[0], files=files)
