在打字稿中获取aws-cdk错误

Question

如何解决类型记录中的这些错误--我已经用cdk innit app --language typescript创建了这些错误。Vscode在配置中突出显示timeout和expires属性。

我在lib文件夹中的构造函数是

import * as cdk from "@aws-cdk/core";
import * as appsync from "@aws-cdk/aws-appsync";
import * as lambda from "@aws-cdk/aws-lambda";

export class Step03GraphQlStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const api = new appsync.GraphqlApi(this, "GRAPHQL_API", {
      name: "cdk-api",
      schema: appsync.Schema.fromAsset("graphql/schema.gql"), 
      authorizationConfig: {
        defaultAuthorization: {
          authorizationType: appsync.AuthorizationType.API_KEY, 
           apiKeyConfig: {
            expires: cdk.Expiration.after(cdk.Duration.days(365)), 
           },
        },
      },
      xrayEnabled: true, 
    });
    new cdk.CfnOutput(this, "APIGraphQlURL", {
      value: api.graphqlUrl,
    });
    new cdk.CfnOutput(this, "GraphQLAPIKey", {
      value: api.apiKey || "",
    });
    const lambda_function = new lambda.Function(this, "LambdaFucntion", {
      runtime: lambda.Runtime.NODEJS_12_X, 
      code: lambda.Code.fromAsset("lambda"), 
      handler: "index.handler", ///specfic fucntion in specific file
      timeout: cdk.Duration.seconds(10), 
    });
    const lambda_data_source = api.addLambdaDataSource(
      "lamdaDataSource",
      lambda_function
    );
    lambda_data_source.createResolver({
      typeName: "Query",
      fieldName: "notes",
    });

    lambda_data_source.createResolver({
      typeName: "Query",
      fieldName: "customNote",
    });
  }
}

在运行tsc时，我会得到这些错误。

将包更新为相同版本的

"dependencies": {
    "@aws-cdk/aws-appsync": "^1.121.0",
    "@aws-cdk/aws-lambda": "^1.121.0",
    "@aws-cdk/core": "1.121.0",
    "source-map-support": "^0.5.16"
  }

确保

在package.json

• have中，
• 中的@aws-cdk/core、@aws-cdk/aws-appsync、@aws-cdk/aws-lambda与您的开发环境中的cdk具有相同的版本，与您在项目中定义的包相同或更高。(全局npm高于或等于您的项目)
