Chart.js won't show data if I remove console.log()

Question

If I try to log something else it again stops working. I tried putting it at the end of the function and it works. It has to be there. What's going on?

  async function fetchData() {
    const response = await client.query(query).toPromise();
    setPoolSnapshots(response.data.poolSnapshots);
    console.log(poolSnapshots[0].totalLiquidity); //breaks without this line.
    poolSnapshots?.map((poolInfo, _index) => (
      dates.push(poolInfo.timestamp),
      swapFeesEarned.push(poolInfo.swapFees24h)
    ))
    swapFeesEarned?.map((swapFee, _index) => (
      swapFeesApr.push((swapFee *365) / poolSnapshots[_index].totalLiquidity * 100)
    ))
    dates?.map((date, _index) => (
      dates[_index] = new Date(date * 1000).toLocaleDateString()
    ))
  };
