Bug Description

Been using your chat-exporter for a while and it has been great, had the issue when I upgraded to discord.py 2.0+ but fixed the issue and it had been running smoothly until today.

Was archiving as I normally do and for some reason it threw me a NoneType error which was very odd since other channels in the same category worked without a hitch. My guess is a perms issue but im not too sure, hoping maybe you would have some insight into this issue.

Thanks!

Hey!

Just checking out the issue you faced, seems to be something to do with the TextChannel object you passed through perhaps wasn't cached(?). Quite unsure on how else/or even if an un-cached TextChannel relates to None.

I'm a little baffled, but it's not anything to do with chat-exporter but perhaps discord.py or a slip up by yourself (not sure how you pass the channel in).

had the issue when I upgraded to discord.py 2.0+ but fixed the issue and it had been running smoothly until today.

What issue was that?

[the-jolley-boy]

My guess was an issue on discords end, not even discord.py. I think I may just accept that I cannot archive this channel since it is an issue that I only have faced on one channel and I have archived like 75+ by now without any issue.

Thanks for the reply I think I will just close this bug.
