使用AWS Amplify和CDK创建自定义资源

我正在尝试使用AWS CDK在AWS Amplify中创建一个自定义资源。而且,我正在尝试使用现有的lambda函数作为提供程序事件处理程序。

当我这样做的时候 amplify push 资源创建失败,没有任何有用的信息。我在这里做错了什么?如何解决此问题?

import * as cdk from '@aws-cdk/core';
import * as AmplifyHelpers from '@aws-amplify/cli-extensibility-helper';
import * as cr from "@aws-cdk/custom-resources";
import * as logs from "@aws-cdk/aws-logs";
import * as lambda from '@aws-cdk/aws-lambda';

import { AmplifyDependentResourcesAttributes } from "../../types/amplify-dependent-resources-ref"

export class cdkStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps, amplifyResourceProps?: AmplifyHelpers.AmplifyResourceProps) {
    super(scope, id, props);
    /* Do not remove - Amplify CLI automatically injects the current deployment environment in this input parameter */
    new cdk.CfnParameter(this, 'env', {
      type: 'String',
      description: 'Current Amplify CLI env name',
    });

    const dependencies: AmplifyDependentResourcesAttributes = AmplifyHelpers.addResourceDependency(this,
      amplifyResourceProps.category,
      amplifyResourceProps.resourceName,
      [{
        category: "function",
        resourceName: "myFunction" 
      }] 
    );


    const myFunctionArn = cdk.Fn.ref(dependencies.function.myFunction.Arn);
    const importedLambda = lambda.Function.fromFunctionArn(this, "importedLambda", myFunctionArn);
    
    const provider = new cr.Provider(this, "MyCustomResourceProvider", {
      onEventHandler: importedLambda,
      logRetention: logs.RetentionDays.ONE_DAY,
    })

    new cdk.CustomResource(this, "MyCustomResource", {
      serviceToken: provider.serviceToken
    })
  }
}

以下是我得到的错误:

CREATE_FAILED custommyCustomResourceXXXX AWS::CloudFormation::Stack参数:[AssetParametersXXXX,…..]必须有值。
