AttributeError: 'NoneType' object has no attribute 'text_channels'

When a DM is sent to the bot, it emoji reacts with ✅, but the message isn't being displayed as a channel in the server. The bot-info channel is available, though. The following error(s) keep occurring in Heroku when a message is sent to the bot.

Have you figured out a solution for this? I am having the same issue. @peter-russell

[peter-russell]

No, still doesn't work. @Celtics2034

So, I looked into this, the issue appears to be that the bot is not correctly picking up the GUILD_ID from the env variable. I haven't figured out why that is, but I have confirmed that deploying it with the GUILD_ID hardcoded here seems to work just fine.

@csojinb this actually only happens if you added the bot to the server after you started it. This is because when the bot starts it checks the guilds that it currently is in, and finds the guild from the provided guild_id and stores it in self.guild. So if you start the bot before you added the stored attribute is set to None. I fixed this issue just now by making self.guild a property.
