【问题描述】：

我是 Amplify 的新手，我正在尝试建立一个相当复杂的架构。当我运行放大推送时，我得到的唯一响应是......

An error occurred when pushing the resources to the cloud

这发生在通知它将创建资源并询问我是否要继续之后。我删除了大部分架构并仅使用一个模型再次尝试并且它有效，所以我的架构中某处存在问题......我猜？我没有看到任何地方可以检查它。

这是架构

type Article
  @model
  @key(name: "bySource", fields: ["sourceId", "dateWritten"]) 
  id: ID!
  link: AWSURL!
  title: String!
  dateWritten: String!
  createdAt: String!
  data: AWSJSON!
  approved: Boolean!
  admin: Boolean!
  creatorId: ID!
  creator: User @connection(fields: ["creatorId"])
  sourceId: ID!
  source: Source @connection(fields: ["sourceId"])
  tagArtCons: [TagArtCon]
    @connection(keyName: "byArticle", fields: ["articleId"])


type Tag @model @key(name: "byFrontPage", fields: ["frontpage"]) 
  id: ID!
  name: String!
  createdAt: String!
  creatorId: ID!
  data: AWSJSON!
  frontpage: String
  official: Boolean!
  tagArtConns: [TagArtCon] @connection(keyName: "byTag", fields: ["tagId"])


type TagArtCon
  @model
  @key(name: "byTag", fields: ["tagId"])
  @key(name: "byArticle", fields: ["articleId"]) 
  id: ID!
  tagId: ID!
  articleId: ID!
  creatorId: ID!
  createdAt: String!
  article: Article @connection(fields: ["articleId"])
  tag: Tag @connection(fields: ["tagId"])
  parentRelations: [TagRelation]
    @connection(keyName: "byParent", fields: ["tagId"])
  childRelations: [TagRelation]
    @connection(keyName: "byChild", fields: ["tagId"])


type TagRelation
  @model
  @key(name: "byParent", fields: ["parentId"])
  @key(name: "byChild", fields: ["childId"]) 
  id: ID!
  parentId: ID!
  childId: ID!
  creatorId: ID!
  createdAt: String!
  parentTag: Tag @connection(fields: ["parentId"])
  childTag: Tag @connection(fields: ["childId"])


type Source @model 
  id: ID!
  sourceName: String!
  sourceUrl: String!
  sourceImage: String!
  creatorId: ID!
  articles: [Article] @connection(keyName: "bySource", fields: ["id"])


type User @model 
  id: ID!
  userName: String!
  userImage: String!
  admin: Boolean!
  createdAt: String!
  data: AWSJSON

我想要做的是拥有一堆文章和一堆标签。标签代表类别，人等。我有以下表格

文章， 标签， 一个表，其中每个条目将一篇文章与一个标签联系起来 持有父/子关系的标签之间的关系表 仅包含文章来源数据的源表 一个用户表

我在某个地方犯了一个错误，架构不起作用，它没有告诉我原因。我会继续简化这个，直到我希望能解决这个问题，但我真的很感激任何帮助，因为我是新手。谢谢。

【参考方案1】：

终于找到问题了。有一个地方我尝试使用“articleId”，一个地方我尝试使用“tagId”，两者都应该是“id”。
