Heroku + Node.JS (express) — ошибка приложения

Я пишу базовый узел.приложение JS HTTP request&response после пошагового руководства.

После развертывания в Heroku, если я посещаю URL, я получаю «ошибку приложения».

Это уже произошло то же самое. Я подождал некоторое время, удалил приложение Heroku, отодвинул приложение Heroku назад, и оно снова работало нормально.

Затем он снова остановился.

Если я попытаюсь получить и отправить запросы (через Postman), я получу ошибку «503 Service available».

Я прикрепляю журнал Heroku, который говорит мне открыть проблему узла, но локально (localhost:3000) работает нормально.
Ошибка H10 » приложение разбилось»
Возможно, кто-то знает, в чем проблема.

Я подключаю свой узел.код js:

var express = require('express');
var bodyParser = require('body-Parser');
var _ = require('underscore');

var app = express();
var PORT = process.env.PORT || 3000;
var todos = [];
var todoNextId = 1;
app.use(bodyParser.json());

//GET /[root]
app.get('/', function (req, res) {
    res.send('Todo API Root');
});

//GET /todos
app.get('/todos', function (req, res) {
    res.json(todos);
});

//GET /todos/:id
app.get('/todos/:id', function (req, res) {
    var todoId = parseInt(req.params.id);
    var matchedToDo = _.findWhere(todos,  {id: todoId});

    if (matchedToDo) {
        res.json(matchedToDo);
    } else {
        res.status(404).send();
    }
});

//POST /todos
app.post('/todos', function (req, res) {
    var body = _.pick(req.body, 'description', 'completed');

    if (!_.isBoolean(body.completed) || !_.isString(body.description) || body.description.trim().length === 0) {
        return res.status(400).send();
    }

    body.description = body.description.trim();

    body.id = todoNextId++;

    todos.push(body);

    res.json(body);
});

app.listen(PORT, function (){
console.log('Express listening on port ' + PORT);
});

Спасибо за помощь.

  1. у вас неправильная зависимость. body-Parserдолжно быть body-parser. малый » p «не столичный «P».
