sails 中的 Create 方法创建了新记录，但 return 请求错误
Create method in sails makes a new record but return bad Request
我有一个名为服务的模型

这是我添加服务的动作文件
出于某种原因，await Services.create 无法正常工作，并且由于未定义 serviceRecord，它会返回此 badRequest 错误。但是，当我转而使用 promises 这是 exec here 时，我看到正在创建记录，但作为 exec 中第二个参数的结果也未定义。
由于必须将studioId推入服务中，所以在做记录时只好将其包含进去，虽然这也是显示badRequest，但它是将记录放入数据库中。
如果有人能告诉我问题的原因是什么，我将不胜感激。我检查了我放入服务模型的参数类型，它们确实匹配，serviceName 是字符串，creditCost 和 price 是数字。

我该怎么做才能解决这个问题？非常感谢任何帮助。
如 documentation for Waterline's create method 中所述，如果您想要新创建记录的副本，则需要链接 .fetch() 方法或 .meta({ fetch: true })
像下面这样的事情应该做：
let serviceRecord = await Services.create({
nameService: newNameService,
creditCost,
price
}).fetch();
sails.log.info(serviceRecord);
新版Sails使用.create()
需要添加.fetch()回传记录

var newUser = await User.create({ fullName: 'Alice McBailey' }).fetch();
