discord bot -- IndexError: list index out of range
discord bot -- IndexError: list index out of range
我编写了一个 discord 机器人，当用户对消息下的表情符号做出反应时，它会为用户提供一个角色。 （反应角色）
如果我使用命令 !reactadd 创建反应角色，那么机器人会保存它，我可以使用命令 !reactremove 再次删除数据库中的条目。
但如果用户对消息下方的表情符号作出反应，则该用户不会获得该角色。
相反，我收到以下错误消息：
Ignoring exception in on_raw_reaction_add

第 34、52 和 62 行存在同样的问题。bot 没有找到数据库条目。
我也不知道为什么。

第 24、34、52 和 62 行必须如下所示：
