AWS secret retrieval issue nodeJs

[Manoj-Chakladar]

Hello everyone,
I am using the below nodejs code to retrieve the secret. but i am not getting the response. i am not sure if i have to use await here if yes then how and where. Also if i am making some other mistake in this code then please guide me. i have also attached trackers using console.log to see where the compiler is going. I am also attaching the output. Please provide me your guidance. I am new with both nodejs and AWS.
Thank you.
code:

exports.handler = async(event)=>{
// Use this code snippet in your app.
// If you need more information about configurations or implementing the sample code, visit the AWS docs:
// https://aws.amazon.com/developers/getting-started/nodejs/

// Load the AWS SDK
var AWS = require('aws-sdk'),
region = "us-east-1",
secretName = "MySecret",
secret,
decodedBinarySecret;
console.log(region);
// Create a Secrets Manager client
var client = new AWS.SecretsManager({
region: region
});

// In this sample we only handle the specific exceptions for the 'GetSecretValue' API.
// See https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_GetSecretValue.html
// We rethrow the exception by default.

console.log("start");
client.getSecretValue({SecretId: secretName}, function(err, data) {
console.log("1");
if (err) {
if (err.code === 'DecryptionFailureException')
// Secrets Manager can't decrypt the protected secret text using the provided KMS key.
// Deal with the exception here, and/or rethrow at your discretion.
throw err;
else if (err.code === 'InternalServiceErrorException')
// An error occurred on the server side.
// Deal with the exception here, and/or rethrow at your discretion.
throw err;
else if (err.code === 'InvalidParameterException')
// You provided an invalid value for a parameter.
// Deal with the exception here, and/or rethrow at your discretion.
throw err;
else if (err.code === 'InvalidRequestException')
// You provided a parameter value that is not valid for the current state of the resource.
// Deal with the exception here, and/or rethrow at your discretion.
throw err;
else if (err.code === 'ResourceNotFoundException')
// We can't find the resource that you asked for.
// Deal with the exception here, and/or rethrow at your discretion.
throw err;
}
else {
// Decrypts secret using the associated KMS CMK.
// Depending on whether the secret is a string or binary, one of these fields will be populated.
console.log("secret found");
if ('SecretString' in data) {
secret = data.SecretString;
console.log("storing secret");

    } else {
        console.log(4);
        let buff = new Buffer(data.SecretBinary, 'base64');
        decodedBinarySecret = buff.toString('ascii');
    }
}


// Your code goes here.

});
console.log("end");
const response ={
body: JSON.stringify(secret),
};
return response;
};

Hi Manoj,
I'm the new tech writer for Secrets Manager. Do you still need help with this issue?
