Hello everyone!
i need help! i am trying to inherit a constructor from the file lazy_barcode_cache.js and Is not working, I tried with patch but nothing happends. 

export default class LazyBarcodeCache {

    constructor(cacheData, params) {

        this.rpc = params.rpc;

        this.dbIdCache = {}; // Cache by model + id

        this.dbBarcodeCache = {}; // Cache by model + barcode

        this.missingBarcode = new Set(); // Used as a cache by `_getMissingRecord`

        this.barcodeFieldByModel = {

            'stock.location': 'barcode',

            'product.product': 'barcode',

            'product.packaging': 'barcode',

            'stock.package.type': 'barcode',

            'stock.picking': 'name',

            'stock.quant.package': 'name',

            'stock.lot': 'name', // Also ref, should take in account multiple fields ?

        };

        this.gs1LengthsByModel = {

            'product.product': 14,

            'product.packaging': 14,

            'stock.location': 13,

            'stock.quant.package': 18,

        };

        // If there is only one active barcode nomenclature, set the cache to be compliant with it.

        if (cacheData['barcode.nomenclature'].length === 1) {

            this.nomenclature = cacheData['barcode.nomenclature'][0];

        }

        this.setCache(cacheData);

    }

thats the one i need to inherit, and the only change i need to do is change this:
"

            'stock.lot': 'name', 

to :

            'stock.lot': 'barcode_lot',

if somebody could help i will be super grateful. 

Greetings!
