If you are using LocalStack to run DynamoDB, I believe the correct command to use the LocalStack network for SAM is:

sam local start-api --env-vars env.json --docker-network localstack_default

And in your code, the LocalStack hostname should be localstack_localstack_1

const dynamoDbDocumentClient = new AWS.DynamoDB.DocumentClient({
  endpoint: process.env.AWS_SAM_LOCAL ?
    'http://localstack_localstack_1:4569' :
    undefined,
});

However, I launched LocalStack using docker-compose up. Using the pip CLI tool to launch LocalStack may result in different identifiers.
