Catching errors in Espruino Modules (SX127x)

Hi Robin 🙂!

It's uploaded from the right-hand side, then uploaded to Flash using the "Send to Espruino" button in the IDE.

I have boiled down the code to this (right-hand side):

// *************************************************************
// *** CONST / VARS
// *************************************************************

// Pins
const PIN_RESET = D17;
const PIN_CS = D4;
const PIN_SCK = D5;
const PIN_MISO = D19;
const PIN_MOSI = D23;

let sx;

// *************************************************************
// *** MAIN
// *************************************************************

/*
 * Called on boot
 */
function onInit() {

    try {
        SPI1.setup({ sck: PIN_SCK, miso: PIN_MISO, mosi: PIN_MOSI });

        sx = require('SX127x').connect({
            spi: SPI1,
            cs: PIN_CS,
            rst: PIN_RESET
        });

    } catch (e) {
        console.log('e: ', e);
    }

}

Should this be taken literally as actual error text?

No, the error is always as shown below:

Uncaught Error: Radio not found!
 at line 1 col 65
...ow Error("Radio not found!");this.setOpMode(0);this.mask(1,1...

Persusing the source will reveal what var objects are created as the module is fetched/parsed. Maybe a conditional test against 'undefined' or what might be expected as those are initialized, and/or throw your own user defined error to catch?

I don't quite understand what you are suggesting 🙂. Which properties could I test against undefined? I mean the error is happening inside the Espruino module, and apparently I'm unable to catch it externally. Modules are not my strongest side, but should't I be able to do that?--I mean, why throw an error if you are prevented from handling it 🤔..

Thanks for taking the time to help 😁!
