Frequently Asked Questions.
There are four main reasons to why you received this message:
1. InviteManager cannot see the channel to which the invitation is directed. (Permission issues can be easily solved by granting the administrator role to InviteManager).
2. Multiple people joined at the same time.
3. The invites made are not being registered by discord.
4: The bot has just restarted, and the invitation from your server was not in the InviteManager internal cache at the time. This is only temporary. This should only happen once after the bot restarts.
Every roles you want InviteManager to give must be under the bot's role. You also need to make sure that the bot has the permission to grant roles.
All required permissions for InviteManager are required for some reason, so please be careful about which permissions you remove. If you remove permissions, it is likely to make some features of InviteManager non-functional.
