拥有正确权限的Discord Bot无法分配角色问题求助

遇到的异常：

discord.errors.Forbidden: 403 Forbidden (error code: 50013): Missing Permissions

Bot已通过管理员权限邀请至服务器，可执行修改成员昵称等管理员操作，但无法为非所有者/管理员的普通成员编辑或分配角色，触发上述权限错误。奇怪的是，手动以Bot角色视角查看服务器时，角色编辑功能是可用的，但Bot自身执行代码时却失败。

已尝试的修复操作 #

• 确认Bot分配的是服务器内的有效角色，将目标角色与服务器可分配角色列表做过比对
• 尝试过member.add_roles()等不同的角色编辑方法，确认问题属于权限范畴，而非Pycord模块本身的问题
