[AWS Javascript SDK V3] How to activate debug log?

I'm using below sample code to log the verbose information of AWS JS SDK v3.

import { DescribeParametersCommand, SSMClient } from "@aws-sdk/client-ssm";
import * as log4js from "log4js";

log4js.configure({
  appenders: { cheese: { type: "file", filename: "cheese.log" } },
  categories: { default: { appenders: ["cheese"], level: "error" } },
});

const logger = log4js.getLogger();
logger.level = "debug";

async function main() {
  const ssmClient = new SSMClient({
    logger: logger,
  });
  const parameters = await ssmClient.send(new DescribeParametersCommand({}));
  console.log(parameters);
}

Hi there,

Thank you for reaching out to us.

1. Please check this link to enable Logging AWS SDK for JavaScript Calls. (Version 2)

https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/logging-sdk-calls.html

To turn on the logger and print log entries in the console, add the following statement to your code. [ AWS.config.logger = console; ]

3. For AWS CLI, you can add " --debug " at the end of the command as well. [Check the example on the link below]

I hope this helps! Thank you!
