How to do a 301 redirect from an AWS lambda function

aws-lambda-redirect.js

exports.handler = (event, context, callback) => {
   const response = {
    statusCode: 301,
    headers: {
      Location: 'https://google.com',
    }
  };

  return callback(null, response);
}

For those using API Gateway + Lambda, I followed this: https://aws.amazon.com/premiumsupport/knowledge-center/malformed-502-api-gateway/

const response = {
    "statusCode": 200,
    "headers": {
        "my_header": "my_value"
    },
    "body": JSON.stringify(responseBody),
    "isBase64Encoded": false
};

The four fields of statusCode, headers, body, and isBase64Encoded were required
