[ERROR] getHistoricalRates, memory leak : FATAL ERROR - JavaScript heap out of memory

[dawadam]

Hi,
I'm trying to retrieve the list of candles.
When the time reaches the "now" time period, the getHistoricalRates method freezes and nodejs has a fatal error :

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

Error is not catchable, it's memory leak.

My code is just that :

import { getHistoricalRates } from "dukascopy-node"

// function
const start = async function () {

    // config
    const configRequest: any = {
        instrument: 'eurusd',
        priceType: 'bid',
        dates: { from: 1720100340000, to: 1720112340000 },
        timeframe: 'm1',
        format: 'json',
        useCache: true,
        cacheFolderPath: './cache/dukascopy',
        ignoreFlats: false,
        retryOnEmpty: true,
        retryCount: 2
    }

    // log
    console.log('configRequest', configRequest)

    try {
        // fetching
        const dataBid = await getHistoricalRates(configRequest);
        console.log('dataBid', dataBid)
    } catch (err) {
        console.error(err)
    }

}

// start
start()

It's possible it working now, because the probleme comes from the time :

(dates: { from: 1720100340000, to: 1720112340000 }

The fatal error appears after the "now" time period, please add security to generate a normal catchable error.
