headerSent undefined

[b-hdev]

whenever I try to start the bot it presents this error, but I never saw this error happen.
I'm still starting in this part of the express

node src/index.js

TypeError: Cannot read property 'headersSent' of undefined

Hi @Hellpme sorry you are having this issue. Can you provide the contents of index.js so we can reproduce the issue to help track down the cause?

const express = require('express');
const app = express();
const PORT = 3000;

module.exports = (client) => {
    //Pagina inicial
    app.get('/', (req, res) => {
        res.type('text/plain');
        res.send(`[Servidor API] de ${client.user.username}
        \n/Estatísticas - Status básico do bot
        \n/Comandos - Lista de comandos e suas categorias`);
    })
    //Estatísticas do Bot!
    .use('./statistics', require('./statistics'))(client)
    //Lista de comandos
    .use('.commands', require('./commands'))(client)
    //Confirmando se os Web Scrapers não estão sendo usados
    .use('/guilds', require('./guilds'))(client)
    .get('/robots.txt', function(req, res) {
            res.type('text/plain');
            res.send('User-agent: *\nallow: /\n\nUser-agent: *\ndisallow: /dashboard');
    })
    .get('*', async function(req, res) {
        res.send('Não há nada aqui Zzz');
    })
    //Iniciando o servidor
    .listen(PORT, () => {
        client.logger.ready(`Estatísticas da [API] carregado na porta ${PORT}`);
    });
}

Hi @Hellpme I believe the issue is that you have your parenthesis in the wrong order in a few places. For example, instead of .use('./statistics', require('./statistics'))(client) I believe you meant to write .use('./statistics', require('./statistics')(client))
