Debugging Express.js Applications

The task with id 1 exists, yet this route answers that it does not:

const tasks = [
  { id: 1, title: 'Write tests', done: false },
  { id: 2, title: 'Read the Express 5 migration guide', done: true },
];

app.get('/tasks/:id', (req, res) => {
  const task = tasks.find((t) => t.id === req.params.id);
  if (!task) {
    return res.status(404).json({ error: 'Task not found' });
  }
  res.json(task);
});

GET /tasks/1 HTTP/1.1

HTTP/1.1 404 Not Found

{"error":"Task not found"}
