Ckeditor Undefined no Nodejs

Question

I’m studying Nodejs and I have a problem with Ckeditor.

I am unable to pass the text information written within the textarea to the backend. He creates the id within the materials, but the content of the editor1 comes as undefined.

I’m reading the documentation and I haven’t been able to figure out how to solve it yet (since I don’t have enough wit yet). I’ve tried the request of editor1 for params and headers to see if that was it, but it didn’t work either.

Follow the HTML code:

<div class="entry">
    <script src="https://cdn.ckeditor.com/4.9.1/standard/ckeditor.js"></script>
    <h1>Teste</h1>
    <div class="body">
        <form action="http://localhost:3333/post-blog/cadastrar" method="post">
            <textarea name="editor1"></textarea>
            <button class="btn-cadastro">Cadastrar</button>
        </form>
        <script>
            CKEDITOR.replace('editor1');
        </script>
    </div>
</div>

And the Nodejs code:

const express = require('express');
const {
  v4: uuidv4
} = require('uuid');

const app = express();

app.use(express.json());

const materias = [];
app.post('/post-blog/cadastrar', (request, response) => {
  const {
    editor1
  } = request.body;
  const materia = {
    id: uuidv4(),
    conteudo: editor1
  };

  materias.push(materia);
  return console.log(editor1);
})
app.listen(3333);
