Configuring region in Node.js AWS SDK

Question

Can someone explain how to fix a missing config error with Node.js? I\'ve followed all the examples from the aws doc page but I still get this error no matter what.

Answer 1

I had the same issue "Missing region in config" and in my case it was that, unlike in the CLI or Python SDK, the Node SDK won't read from the ~\.aws\config file.

To solve this, you have three options:

1. Configure it programmatically (hard-coded): AWS.config.update({region:'your-region'});

2. Use an environment variable. While the CLI uses AWS_DEFAULT_REGION, the Node SDK uses AWS_REGION.

3. Load from a JSON file using AWS.config.loadFromPath('./config.json');

JSON format:

{ 
    "accessKeyId": "akid", 
    "secretAccessKey": "secret", 
    "region": "us-east-1" 
}
