Recivieng error 500 when deploy Django rest-Vue project on Heroku - django

Question

I'm been able to deploy my first project to heroku.
The API is this: https://segmentacion-app.herokuapp.com/cluster/, and the front is this: https://cluster-app-wedo.herokuapp.com/, the problem appears when I try to consume the api, I receive this: Failed to load resource: the server responded with a status of 500 (Internal Server Error) Error: Request failed with status code 500 at t.exports (createError.js:16) at t.exports (settle.js:17) at XMLHttpRequest.p.onreadystatechange (xhr.js:61) Home.vue:598, can I have some feedback about what i've missed?
Home.vue
let datos = await axios.post('https://segmentacion-app.herokuapp.com/cluster/',json)
.then(response => { ...

Answer 1

The problem was on server.js file, now is:
const express = require('express');
const path = require('path');
const serveStatic = require('serve-static');
app = express();
app.use(serveStatic(path.join(__dirname, 'dist')));
app.get(/.*/, function(req, res) {
res.sendfile(__dirname + '/dist/index.html');
});
const port = process.env.PORT || 8080;
app.listen(port);
console.log("Server started..." + port);
Another thing important is to set server to production:
heroku config:set NODE_ENV=production --app <YOUR-PROJECT-NAME-HERE>
