Issue with loopback middleware

This repo contains some custom error handling middleware attached to the loopback framework. The purpose of this is to show a potential bug with middleware not being run.

The issue appears when there is a 404 error on an api with the correct restApiRoot set.

Examples

GET /api/nonexistent - Will not call middleware
GET /another/nonexistent - Will call the middleware properly

Prep

npm install
npm install -g mocha

Failing Test 1

export NODE_ENV=staging

Failing Test 2

export NODE_ENV=production
mocha test
