My problem
I am writing a simple js function that reads some information from AWS CloudWatch Logs.
Following the answer at Configuring region in Node.js AWS SDK, and the AWS nodejs SDK documentation, I came up with the following:
Code
var AWS = require('aws-sdk');
var cloudwatchlogs = new AWS.CloudWatchLogs();
console.log(AWS.config.region) // Undefined
AWS.config.region = 'eu-central-1' // Define the region with dot notation
console.log(AWS.config.region) . // eu-central-1
AWS.config.update({region:'eu-central-1'}); // Another way to update
console.log(AWS.config.region) . // eu-central-1
var params = {
limit: 0,
// logGroupNamePrefix: 'STRING_VALUE',
// nextToken: 'STRING_VALUE'
};
// This call is failing
cloudwatchlogs.describeLogGroups(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
Output and error
undefined
eu-central-1
eu-central-1

My question
How can I correctly configure the region in the AWS js SDK?
Addendum
Opened an issue on github and got some response.
回答1:
Or, alternatively, you can specify that when creating your cloudwatch object:
var AWS = require('aws-sdk');
var cloudwatchlogs = new AWS.CloudWatchLogs({region: 'eu-central-1'});
回答2:
Write code in following way it will work.
var AWS = require('aws-sdk');
// assign AWS credentials here in following way:
AWS.config.update({
accessKeyId: 'asdjsadkskdskskdk',
secretAccessKey: 'sdsadsissdiidicdsi',
region: 'eu-central-1'
});
var cloudwatchlogs = new AWS.CloudWatchLogs({apiVersion: '2014-03-28'});

Use following.
AWS.config.update({region: 'eu-central-1'});
You can find more information in following link.
