Error handling clarification

[Mark-81]

Following the examples here a snippet of my code:

process.on('uncaughtException', err => {
    console.error((new Date).toUTCString() + ' uncaughtException:', err);
    console.error("Exiting...");
    process.exit(1)
})

// ...

var DB = require('node-adodb'), connection = DB.open('Provider=Microsoft.Jet.OLEDB.4.0;Data Source=pathToDatabase.mdb');

function submit(data, callback) {
    var id = data.id;
    var query = // create query from data values

    connection
        .execute(query)
        .then(data => {
            return callback({ id: id, success: true });
        })
        .catch(error => {
            console.error('submit query failed: ' + error.process.message);
            return callback({ id: id, success: false });
        });
}

So I'm expecting that if the query fails it nicely calls the callback reporting the failure.
To test it, after initialization I suddenly remove the database file. The error is apparently handled:

submit query failed: Impossibile trovare il file pathToDatabase.mdb

but then the program crashes due to an "unhandled error":

Tue, 15 Jan 2019 12:33:23 GMT uncaughtException: { Error: Unhandled "error" event. ([object Object])
Exiting...

I'm running Node v8.12.0 under Windows 7.
I forgot something in the configuration/use of node-adodb?

Some exception throw by cscript, but cscript exception information is bad！

[I don't think is so nice to immediately close an issue without waiting for a while if users have any further question...]

Anyway, I kindly ask an example how to handle such a situation. I understand cscript exception information is bad, but I cannot let my program crash. Would you mind to show m how to change my snippet above in order to correctly catch the exception? Thanks in advance.
