When I add this code to my app.js in the express server
app.get('/*', function (req, res) {
res.sendFile(path.join(publicPath, 'index.html')), function(err) {
if (err) {
res.status(500).send(err)
}
};
})
The console print the following error when I make a request, except fot the signin page which works good.
Type error: cannot read
react-dom.production.min.js:216
TypeError: Cannot read properties of undefined (reading '0')
at Resultados.js:2368:16
Without adding that code lines, the app works okey, except when I refresh the page, because in the browser appear the message cannot get.
Why without the code the app is not returning undefined?

res.sendFile
only sends index.html
file and other files in your public folder are inaccessible. Serve your public folder like this
const path = require('path')
const publicFolder = path.join(__dirname, 'public');
app.use('/*', express.static(publicFolder))
