Answer 1

You can try add newdoc.isNew = true :
//ROUTE CLONA PREVENTIVO
app.post('/preventivi/dbpreventivi/:id/clone' ,accessoSicuro,(req , res) =>{
Preventivi.findOne({
_id: req.params.id
})
.then(preventivo => {
var newdoc = new Preventivi(preventivo);
newdoc._id = mongoose.Types.ObjectId();
newdoc.isNew = true;
newdoc.save();
console.log(newdoc._id)
req.flash("msg_successo", "Preventivo clonato correttamente");
res.redirect("/preventivi/dbpreventivi");
});
});
//fine route clona preventivo

Answer 2

Mine, was using "async map" incorrect way.
I did update some records in a "async map" method like below:
makerOrders.map(async makerOrder => {
....
try {
await Order.findByIdAndUpdate(makerOrder._id, {
remainder: makerOrder.remainder,
});
} catch (error) {
console.log(' order.save(); ' + err);
return err(`Maker order is not updated. ${err}`, 500);
}
...
});
Even using try catch didn't catch the error and it has got 3 days to solve!
Hope help somebody :)
