		NOTES:
		- If another middleware does not handle and swallow errors, then it will bubble all the way up
		and terminate the Lambda invocation with an error. In this case API Gateway would return a default 502 response, and the CORS headers would be lost. To prevent this, you should use the `httpErrorHandler` middleware before the `cors` middleware like this:

		```javascript
		const middy = require('@middy/core')
		const httpErrorHandler = require('@middy/http-error-handler')
		const cors = require('@middy/http-cors')

		const handler = middy((event, context, cb) => {
		throw new createError.UnprocessableEntity()
		})
		handler.use(httpErrorHandler())
		.use(cors())

		// when Lambda runs the handler...
		handler({}, {}, (_, response) => {
		expect(response.headers['Access-Control-Allow-Origin']).toEqual('*')
		expect(response).toEqual({
		statusCode: 422,
		body: 'Unprocessable Entity'
		})
		})
		```
