KeystoneJS中的CastError

Question

虽然我尝试处理模型之间的关系但是我无法更新数据库，但是我收到此错误。

（KeystoneJS）保存更改时出错：在路径“techstack”（CastError）中将值“[object Object]”强制转换为未定义失败

请指导我，谢谢：

这是我的代码：

var keystone = require('keystone');
var Types = keystone.Field.Types;


var TechStack = new keystone.List('TechStack', {
  autokey: { from: 'name', path: 'key', unique: true}
});

TechStack.add({
    name: { type: String, index: true},
    techtitle: { type: Types.Html, wysiwyg: true, height: 50 },
    technology: { type: Types.Html, wysiwyg: true, height: 50 },
    info: { type: Types.Html, wysiwyg: true, height: 50 }
  // typetitle: { type: Types.Html, wysiwyg: true, height: 50 },
});

TechStack.relationship({ref: 'ServiceType', path: 'techstack'});

TechStack.schema.virtual('content.full').get(function() {
    return this.name || this.techtitle || this.technology || this.info          ;
});

TechStack.register();

错误是：
