私は次のコードを持っています:

var AWSXRay = require('aws-xray-sdk');
    var AWS = AWSXRay.captureAWS(require('aws-sdk'));
    const client = AWSXRay.captureAWSClient(new AWS.DynamoDB.DocumentClient({region : 'eu-west-1'}));
    exports.handler = function(event, context, callback) {

        AWSXRay.captureFunc('annotations', function(subsegment){
        subsegment.addAnnotation('User', **);
        subsegment.addAnnotation('Name', **);
      });

         var params = {
            TableName: "****",
            ** all params **
            };
     client.query(params, function(err, data) {
       if (err) console.log(err, err.stack); // an error occurred
       else{
            callback(null,data);
            }
        });
    }

上記のコードを実行すると、次のエラーがスローされます。

Response:
{
  "errorMessage": "service.customizeRequests is not a function",
  "errorType": "TypeError",
  "stackTrace": [
    "Object.<anonymous> (/var/task/index.js:5:24)",
    "Module._compile (module.js:570:32)",
    "Object.Module._extensions..js (module.js:579:10)",
    "Module.load (module.js:487:32)",
    "tryModuleLoad (module.js:446:12)",
    "Function.Module._load (module.js:438:3)",
    "Module.require (module.js:497:17)",
    "require (internal/module.js:20:19)"
  ]
}

以下は関数のログです:

    at require (internal/module.js:20:19)
END

これをどのように解決すればよいですか？

クライアントには .service パブリック変数がありません。とはいえ、これは私のために働いています：

import * as AWS  from 'aws-sdk'
import * as AWSXRay from 'aws-xray-sdk'
import { DocumentClient } from 'aws-sdk/clients/dynamodb'

export class DynDBAccess {
    private readonly docClient: DocumentClient // = new AWS.DynamoDB.DocumentClient(),

    constructor(
        private enableAWSX:boolean,      
    ){
        if(this.enableAWSX)
        {
           logger.info('AWSX: enable')
           const ddbClient = AWSXRay.captureAWSClient(new AWS.DynamoDB({
            ////Uncomment below to use serverless-dynamodb-local
            //region: 'localhost',
            //endpoint: 'http://localhost:8001',
            //accessKeyId: 'DEFAULT_ACCESS_KEY',  // needed if you don't have aws credentials at all in env
            //secretAccessKey: 'DEFAULT_SECRET',
           }));
           this.docClient = new AWS.DynamoDB.DocumentClient({
            service: ddbClient
          });

        }
