When you are using the AWS Node.js SDK, you might encouter the error message :
UnhandledPromiseRejectionWarning: Error: connect ENETUNREACH 169.254.169.254:80 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1145:16).
{:class=“img-responsive”}
This error is likely occuring because the AWS SDK is unable to find your AWS credentials. AWS Documentation has a list of ways you can load credentials in Node.js
Where the credential files are stored depends on your operating system.
on Linux, Unix, and macOS:
~/.aws/credentialson Windows:
C:\Users\USER_NAME\.aws\credentials
In my case, the issue was that I did not have a [default] profile in my aws credentials file. As such, I needed to tell the AWS Node.js SDK which profile to use instead.
Assuming your profile is named `myspecial-profile, here’s how you can do that :
const AWS = require('aws-sdk');
AWS.config.region = 'us-east-1';
var credentials = new AWS.SharedIniFileCredentials({profile: 'myspecial-profile'});
AWS.config.credentials = credentials;
