AWS SDK error wrapper for Error: getaddrinfo ENOTFOUND

[julianpitt]

Hi there,

I'm receiving the following error when running jest-dynalite

AWS SDK error wrapper for Error: getaddrinfo ENOTFOUND sts.local.amazonaws.com

I'm using typescript and the advanced setup

I'm creating my dynamodb document client using the following snippet inside my test suite

const buildDocumentClient = () => getClient({
  endpoint: `http://${process.env['MOCK_DYNAMODB_ENDPOINT']}`,
  tls: false,
  region: "local",
  credentials: {
    accessKeyId: "dummy",
    secretAccessKey: "dummy"
  }
});

I'm currently using the following versions:

• @aws-sdk/client-dynamodb: 3.58.0
• @aws-sdk/lib-dynamodb: 3.58.0
• jest-dynalite: 3.4.4

I've tried the simple setup and using a js setup file with no luck.

What does your getClient function do?

It seems the region: 'local' param is being used in the host amazon is trying to access

[julianpitt]

export function getClient(configuration: DynamoDBClientConfig = {}) {
  const client = new DynamoDBClient(configuration);
  return DynamoDBDocumentClient.from(client, {marshallOptions: {removeUndefinedValues: true}});
}

Just following the docs https://github.com/freshollie/jest-dynalite#update-your-sourcecode

Could you try using a valid region?

[YBogomolov]

For anyone who faced the same issue: this happens if you have a valid AWS_PROFILE environmental variable. Setting process.env.AWS_PROFILE = '' somewhere in your jest.setup.ts/js file resolves this behaviour.

Oh I wonder if I should delete AWS_PROFILE to nothing as part of this library, it feels like it's unrelated?

Well, if you ask me, then probably it's a good idea to do a backup of the original value of process.env.AWS_PROFILE, delete it before the tests, and restore it afterwards. Or just delete it altogether, either way works.

[freshollie]

I'm going to delete and restore AWS_PROFILE when I run any commands against the DB in the library. At least that way the error won't come from within the library but from your own tests if you use still have AWS_PROFILE set
