AppSync with CDK Deploy Failed with ：`命名的'AWSTimeStamp'标量类型没有标量实现`

如何解决AppSync with CDK Deploy Failed with ：`命名的'AWSTimeStamp'标量类型没有标量实现`

语言：打字稿

工具：Appsync 和 CDK

总结：我正在尝试在我的 Graphql 架构中使用标量 AWSTimeStamp

错误信息：

UPDATE_Failed | AWS::AppSync::GraphQLSchema Schema Creation Status is Failed with details: Found 1 problem(s) with the schema: There is no scalar implementation for the named 'AWSTimeStamp' scalar type.

架构文件：

index.graphql

schema {
  query: Query
  mutation: Mutation
}

type Query
type Mutation

scalar AWSTimeStamp

type Address {
  id: ID
  addressNickName: String
  address1: String
  address2: String
  attnTo: String
  city: String
  state: String
  zipCode: String
  country: String
  createdAt: AWSTimeStamp
  updatedAt: AWSTimeStamp
  isActive: Boolean
}

dealership.graphql

extend type Mutation {
  createDealership(input: CreateDealershipInput): DealershipPayload
}

input CreateDealershipInput {
  engineId: ID!
  name: String
  slug: String
  address: AddressInput
}

type DealershipPayload {
  id: ID
  engineId: ID
  name: String
  slug: String
  salesAddressId: ID
  salesAddress: Address
}

input AddressInput {
  addressNickName: String
  address1: String
  address2: String
  attnTo: String
  city: String
  state: String
  zipCode: String
  country: String
}

注意：这两个 graphql 文件会自动合并为一个 schema.graphql

schema.graphql

schema { 
  query: Query 
  mutation: Mutation   
}

type Address {
  id: ID
  addressNickName: String
  address1: String
  address2: String
  attnTo: String
  city: String
  state: String
  zipCode: String
  country: String
  createdAt: AWSTimeStamp
  updatedAt: AWSTimeStamp
  isActive: Boolean
}

input AddressInput {
  addressNickName: String
  address1: String
  address2: String
  attnTo: String
  city: String
  state: String
  zipCode: String
  country: String
}

scalar AWSTimeStamp

input CreateDealershipInput {
  engineId: ID!
  name: String
  slug: String
  address: AddressInput
}

type DealershipPayload {
  id: ID
  engineId: ID
  name: String
  slug: String
  salesAddressId: ID
  salesAddress: Address
}

type Mutation {
  createDealership(input: CreateDealershipInput): DealershipPayload
}

当我删除“标量 AWSTimeStamp”并将 AWSTimeStamp 类型替换为“String”时，部署成功。我不确定是否需要导入某些内容才能使用 AWSTimeStamp 标量。我正在查看此文档 https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-appsync.GraphqlType.html，但如果这实际上是我需要的，我不确定在哪里插入此导入。我对 GraphQL 和 CDK 很陌生。我期待着一些指导！谢谢。

解决方法

您有带有大写 AWSTimeStamp 的 S，但 AppSync 标量类型是带有小写 s 的 AWSTimestamp。 >
