My getBarscode is:

getBars: async (symbolInfo, resolution, periodParams, onHistoryCallback, _onErrorCallback) => {
		const { to, countBack, firstDataRequest } = periodParams;
		const url = `/bars/${symbolInfo.ticker}?countback=${countBack}&end=${to}&resolution=${resolution}&firstdatarequest=${firstDataRequest}`;

		const payload = await fetcher(url);					
		
		let bars = [];	
		if (payload.length) {
			bars = payload.map((el) => {
				return {
					time: el.ts * 1000, // TradingView requires bar time in ms
					low: el.low,
					high: el.high,
					open: el.open,
					close: el.close,
					volume: el.volume,
				};
			});

			// Once all the bars (usually countBack is around 300 bars) the array of candles is returned to the library.				
			onHistoryCallback(bars, { noData: false });
		} else {
			// If no result, return an empty array and specify it to the library by changing the value of `noData` to true.
			onHistoryCallback(bars, { noData: true });				
		}
	},

Someone can help me? I've tried a lot of things, but I am stuck. Thanks a lot.
