TypeScript complaining even the code is correct?

  type TradeSummary = Record<string, {
      symbol: string;
      datetime: string;
      realizedPnl: number;
      commission: number;
    }>;


  const closedTrades = Object.values(transactions.reduce((acc: TradeSummary, curr) => {
    const { symbol, realizedPnl, commission } = curr.info;
    const year = curr.datetime.slice(0, 4);
    const month = curr.datetime.slice(5, 7);
    const day = curr.datetime.slice(8, 10);
    const datetime = `${year}-${month}-${day}`;
  
    const key = `${symbol}_${datetime}`;
  
    if (!acc[key]) {
      acc[key] = { symbol, datetime, realizedPnl: 0, commission: 0};
    }
  
    acc[key].realizedPnl += parseFloat(realizedPnl);
    acc[key].commission += parseFloat(commission);

    acc[key].realizedPnl = parseFloat(acc[key].realizedPnl.toFixed(2))
    acc[key].commission = parseFloat(acc[key].commission.toFixed(2));
  
    return acc;
  }, {}));
