我有一个云形式项目，具有以下配置。

Question

我有以下代码，试图连接到DynamoDB并失败。

    try {
        const client = new DynamoDBClient({
            endpoint: "http://localhost:4566"
        });

        await client.send(new UpdateItemCommand({
            TableName: process.env.dbStorage,
            Key: marshall({id: "test"}),
            ExpressionAttributeValues: marshall({":test": "hello world"}),
            UpdateExpression: "SET test = :test",
        }));
        //
        const x = await client.send(new GetItemCommand({
            TableName: process.env.dbStorage,
            Key: marshall({id: "test"}),
        }))

        console.log("JSON.stringify(x)");
        console.log(JSON.stringify(x));
    } catch (ex) {
        console.log("JSON.stringify(ex)")
        console.log(JSON.stringify(ex))
    }

这是错误。

{
  "errno": -111,
  "code": "ECONNREFUSED",
  "syscall": "connect",
  "address": "127.0.0.1",
  "port": 4566,
  "$metadata": {
    "attempts": 1,
    "totalRetryDelay": 0
  }
}

我还尝试创建客户端而没有任何参数，并且也失败了。

const client = new DynamoDBClient();

这是错误。

{
  "name": "UnrecognizedClientException",
  "$fault": "client",
  "$metadata": {
    "httpStatusCode": 400,
    "requestId": "VAHE0KG1D1UTE9AQNAREF9RJHFVV4KQNSO5AEMVJF66Q9ASUAAJG",
    "attempts": 1,
    "totalRetryDelay": 0
  },
  "__type": "com.amazon.coral.service#UnrecognizedClientException",
  "message": "The security token included in the request is invalid."
}

如何从配置和/或如何访问这些资源来创建DynamoDB资源？

update

我正在使用此端点，似乎可以将客户端连接到localstack。

        const client = new DynamoDBClient({
            endpoint: "http://host.docker.internal:4566",
        });

我在进行A

GetItemCommand时会遇到以下错误
