Discord.py工单机器人按钮点击报错，请求修复指导

错误原因 #

报错TypeError: ticket_embed_.Ticket_Embed_button() missing 1 required positional argument: 'button'是因为按钮回调函数的参数定义不符合Discord.py规范：

• 多余了ctx参数，按钮回调的触发逻辑里不会传入ctx对象
• 参数顺序错误，正确的按钮回调参数顺序应为self, interaction, button

修复步骤及修正后代码 #

关键修改点： #

1. 移除Ticket_Embed_button函数中的ctx参数，调整为正确的参数顺序
2. 将函数内所有ctx.guild替换为interaction.guild，删除重复的消息发送代码（原代码中重复发送了两次工单创建通知）
3. 增加分类不存在的判断，避免机器人崩溃

修正后的完整代码： #

额外说明 #

• 确保服务器中已创建名为Support的分类，否则机器人会提示找不到分类
• 原代码中重复发送了两次工单创建通知，已删除重复部分，避免用户收到两条相同消息
