您需要按如下方式修改您的代码。如果您正确定义了关联，那么您将获得预期的结果。

var user = await db.user.findOne({
  attributes: {
    include: [
      'charges',
      'availability',
      'practice', // 'services',
      'education', // 'user_role',
      'address',
      'user_location'
      // 'isAvailableStatus',
    ]
  },
  include: [
    { model: db.user_role, attributes: role_attributes },
    {
      model: db.user_service,
      as: 'services',
      include: [{ model: db.service_group, as: 'group' }]
    }
  ],
  where: { id: 0 }
});
