If you plan to use Node.js in an AWS Lambda function with an AWS API Gateway and need to have streamlined error objects for easy response parsing, just use `lambda-error`:

```js

var lambdaErr = require('lambda-error');

exports.handle = function(e, ctx, callback) {

  if (!e.name) {

    return callback(

      lambdaErr.BadRequest('Missing name').toString()

    );

  }

  

  ctx.succeed({name: e.name, found: true});

};

```

```js

var lambdaErr = require('lambda-error');

exports.handle = function(e, ctx, callback) {

  if (!e.name) {

    return callback(

      lambdaErr.BadRequest('Missing name').withContext(ctx).toString()

    );

  }

  

  ctx.succeed({name: e.name, found: true});

};

```
