Handling 500 internal server error: channel.history() making cog not work

[SilascBot]

I've written a Discord bot that uses multiple cogs. However a few of my cogs stop working when a discord.errors.DiscordServerError: 500 Internal Server Error (error code: 0): 500: Internal Server Error error is raised.

The functionality of those cogs no longer work until I restart the entire bot, but the other cogs work just fine. From what I can see, this is happening due to using channel.history(). Once the error is raised, channel history does not work obviously and thus the cog "shuts down." Other cogs that do not rely on that function work totally fine after the error (once discord comes back up), so the bot does not shut down - only this specific function for whatever reason.

Here is the full traceback:

I was curious if anyone had any sort of recommendation on handling this? Maybe writing a script to auto-restart the entire bot if this error occurs?

If it matters how I'm using it, here is an example:

@tasks.loop(seconds = 600)
async def mytask(self):
    channel = self.bot.get_channel(channel_id)
    async for message in channel.history():
        #doing stuff here

Thanks for any help!

It's quite likely that you are spamming the server by querying a lot of message history every 10 minutes. Solution: do not use history() inside a task.
