I am trying to insert a new movie to Postgres SQL via postman, but I can not. Is there someone who could help me?

Here are the captures from the postman: enter image description here enter image description here When I post the new movie, there always said: "Cannot POST /api/movies".

Here is my code:

const db = require('./dbconfig');

// Get all movies
const getAllMovies = (req, res) => {
  db.query('SELECT * FROM movies', (err, result) => {
    if (err)
      console.error(err);
    else
      res.json(result.rows)
  })
}

// Get movie by id
const getMovieById = (req, res) => {
  const query = {
    text: 'SELECT * FROM movies WHERE id = $1',
    values: [req.params.id],
  }

  db.query(query, (err, result) => {
    if (err) {
      return console.error('Error executing query', err.stack)
    }
    else {
      if (result.rows.length > 0)
        res.json(result.rows);
      else
        res.status(404).end();
    }
  })
}

// Add new movie
const addMovie = (req, res) => {
  // Extract movie from the request body
  const newMovie = req.body;

  const query = {
    text: 'INSERT INTO movies (title, director, year) VALUES ($1, $2, $3)',
    values: [newMovie.title, newMovie.director, newMovie.year],
  }
  
  db.query(query, (err, res) => {
    if (err) {
      return console.error('Error executing query', err.stack)
    }
  })
  
  res.json(newMovie);
}


  
    res.status(204).end();
  }

module.exports = {
  getAllMovies: getAllMovies,
  getMovieById: getMovieById,
  addMovie: addMovie,
}

// index.js

const express = require('express');
const bodyParser = require('body-parser');
const query = require('./db/movies');

const app = express();
app.use(bodyParser.json());

const port = 3000;

app.get("/api/movies", query.getAllMovies);
app.get("/api/movies/:id", query.getMovieById);
app.post("/api/movies", query.addMovie);

app.listen(port, () => {{}
  console.log(`Server is running on port ${port}.`);
});
