How to configure view engine correctly

[hamza_bouallegue]

Hello !
i developed an app with ACE using React + JSX , when i run my app locally with ngrok it works as expected , now i deployed my app on Heroku and i installed it on my instance but i can’t run it , i got this when i inspect the Heroku logs :

2021-01-11T08:44:24.301934+00:00 app[web.1]: Error: Could not load the component dashboard.jsx. Did you run `npm build to compile your jsx files?

this is my route file

export default function routes(app, addon) {
   

    app.get('/', (req, res) => {
        res.redirect('/atlassian-connect.json');
    });

   
    app.get('/myapp',  addon.authenticate(), (req, res) => {
     
        res.render(
          'dashboard.jsx',
          {
            title: 'Atlassian Connect'
           
          }
        );

    });
}

from app.js file :

const devEnv = app.get('env') === 'development';
app.use(morgan(devEnv ? 'dev' : 'combined'));

// Configure Handlebars
const viewsDir = path.join(__dirname, 'views');
const handlebarsEngine = hbs.express4({partialsDir: viewsDir});
app.engine('hbs', handlebarsEngine);
app.set('view engine', 'hbs');
app.set('views', viewsDir);

// Configure jsx (jsx files should go in views/ and export the root component as the default export)
addServerSideRendering(app, handlebarsEngine);

any help about what i m missing please
