I solved the “getaddrinfo ENOTFOUND xxx.region.amazonaws.com” error

Hi, this is Charu from Games Solution Department, Classmethod.

I am writing this blog to tell the solution for the error "getaddrinfo ENOTFOUND xxx.region.amazonaws.com". I got this error when I was running the lambda function written in TypeScript language.

The Original Code:

The original code which I was trying to run-

import { DynamoDBClient, paginateScan } from "@aws-sdk/client-dynamodb";
import { unmarshall } from "@aws-sdk/util-dynamodb";

const TABLE_NAME = process.env.TABLE_NAME || "";

interface Employee {
  user_id_name: string;
}

const client = new DynamoDBClient({
  region: "ap-northaest-1",
});

const paginatorConfig = {
  client: client,
};

export const handler = async () => {
  let employees: Employee[] = [];

  const params = { TableName: TABLE_NAME };
  const paginator = paginateScan(paginatorConfig, params);

  for await (const page of paginator) {
    if (page.Items) {
      employees.push(
        ...page.Items.map((item) => {
          return unmarshall(item) as Employee;
        })
      );
    }
  }

  return {
    statusCode: 200,
  };
};

This code is to scan the items from the dynamoDB table.

The code looked fine to me but I got the following error-

The Mistake:

If you look closely, there is a mistake in the AWS region spelling-

const client = new DynamoDBClient({
  region: "ap-northaest-1",
});

The actual code snippet should be like this-

const client = new DynamoDBClient({
  region: "ap-northeast-1",
});

Conclusion:

The ENOTFOUND error can happen when the system couldn't resolve the domain name you provided. There can be other reasons too, such as:

The hostname is invalid.

Your network connection is faulty.

Your DNS server is faulty.

The DNS server that handles the domain name is faulty.

I hope your error is resolved.

Thank you for reading!

Happy Learning :)
