Error: ConfigError: Missing region in config
Solution
You must specify a region. You can also configure your region by running "aws configure".This error is a not an DynamoDB specific error, it can happen with any AWS API/CLI/SDK command if you're not having a default AWS region setup in your environment variables or in credentials configuration.
There are a few ways to solve this error:
You can set the AWS_DEFAULT_REGION environment variable to something like "us-east-1" (replace with region you're actually using).
export AWS_DEFAULT_REGION=us-east-1
If using AWS profiles, you can include the region in the ~/.aws/config file. Make sure following entry exists in this file:
[profile my-profile] region=us-east-1
If using CLI, you can end your command with --region=[region]
aws dynamodb list-tables --endpoint-url http://localhost:8000 --region=us-east-1
If using SDK, you pass the region you want to use into the DynamoDB service construtor. In Node.js case, it will look like this:
import { DynamoDB } from "aws-sdk" const ddb = new DynamoDB({ region: 'us-east-1' })
