heroku desc部署错误=“没有运行Web进程”

我正在将我的应用程序部署到heroku中，它是用Node.js编写的，主要脚本是main.js看起来像这样

var fs = require('fs');
var file = fs.readFileSync('count.json');
var Words = JSON.parse(file);

const express = require('express');
const app = express();
app.listen(process.env.PORT || 3000, () => console.log('we are listeining'));
app.use(express.static('public'));
app.use(express.json({ limit : '1mb' })); 


app.get('/add/:word', addWord);

function addWord(request, response) {
  var data = request.params;
  var word = data.word;
  var reply;
  var found = false;
  for (i = 0; i < Words.length; i++){
    if (Words[i].type == word){
      Words[i].count++;
      found = true;
      break;
    }
  }

if (!found) {
  Words.push({"type": word , "count": 1});
}

  var x = JSON.stringify(Words, null, 2);
  fs.writeFile('count.json', x, finished);

  function finished(){
    console.log('Yay')
  }
    /* 
    console.log(Words[word]); */

/*     response.send(reply); */
  }

我也已经将Procfile部署为

worker: node main.js

但是仍然有这个问题，这是heroku的日志

您正在运行Web服务器，因此在Procfile中设置为web而不是worker。

web: node main.js

Heroku将HTTP请求路由到以web名称开头的进程。
