Describe the bug

I am using AWS Lambda with the Node v18 runtime. I am using several @aws-sdk/* packages, which should be globally available in the Node v18 runtime of AWS Lambda. This holds true for most packages. However, I get this error when trying to use @aws-sdk/util-retry. The code looks like this:

import {
  DynamoDBClient,
  UpdateItemCommand,
  QueryCommand
} from "@aws-sdk/client-dynamodb";
import { ConfiguredRetryStrategy } from "@aws-sdk/util-retry";
import {
  CloudWatchClient,
  PutMetricDataCommand
} from "@aws-sdk/client-cloudwatch";

and the error is:

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@aws-sdk/util-retry' imported from /var/task/index.mjs

How can I know in advance which @aws-sdk/* packages are available at runtime and which are not?

cf. #4401

SDK version number

@aws-sdk/util-retry

Which JavaScript Runtime is this issue in?

Node.js

Details of the browser/Node.js/ReactNative version

nodejs18.x (whatever AWS Lambda uses)

Reproduction Steps

Use @aws-sdk/util-retry in ESM Node v18 Lambda runtime.

Observed Behavior

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@aws-sdk/util-retry' imported from /var/task/index.mjs

Expected Behavior

Import works

Hi @albertodiazdorado, this is not an issue really. @aws-sdk/util-retry was introduced in version 3.222.0, which can be confirmed here, and the version embedded in lambda is 3.188.0, which can be seen here. Also, @aws-sdk/util-retry has been moved to @smith/util-retry. Something you can do is to either, upload a node_modules folder with this package installed, or create a lambda layer and also upload this dependency. The exact dependency name is @smithy/util-retry.

Here is the documentation for lambda layers, in case you would opt for this option and need guidance regarding.

Please let me know if that helps!

Thanks!
