How to fix recent node.js errors from my apps? - node.js

Question

const express = require("express");
const path = require("path");
var hbs = require("express-handlebars");
const morgan = require("morgan");
const middlewares = require("./middlewares/middlewares");
const PORT = process.env.PORT || 3002;
var app = express();
// setup static file service
app.use(express.static(path.join(__dirname, "static")));
//Setup app port
app.set("port", process.env.PORT || PORT);
// setup handlebars and the view engine for res.render calls
app.set("view engine", "html");
app.engine(
"html",
hbs({
extname: "html",
defaultView: "default",
layoutsDir: __dirname + "/views/layouts/",
partialsDir: __dirname + "/views/partials/"
})
);
app.get("/", (req, res) => {
res.send("Hello world");
});
app.use(morgan("common"));
app.use(middlewares.errorHandler);
app.use(middlewares.ignoreFavicon);
app.use(middlewares.notFound);
var server = app.listen(app.get("port"), () =>
console.log(`Server started...Listening on port: ${PORT}`)
);
This is my basic server setup. Whenever I request a route I get the following errors in my console. I had to add middleware ignoring this route as well. "GET /favicon.ico HTTP/1.1"
Uncaught TypeError: Cannot convert undefined or null to object

[Honeybadger] Unable to send error report: no API key has been configured.

Answer 1

is there more of a stack trace? Also, when you say "console", do you mean in the Node console, or in the browser console? It looks like the log message is from our client-side JavaScript package, which I would expect in the browser. If you're catching errors in your Node application, you should use our Node.js package.
In honeybadger.js, ___hb can sometimes appear in stack traces because the function was wrapped by our library, but the error is often still in your project code. I would suggest configuring Honeybadger with an API key if you're trying to diagnose errors in production.
