promise.all似乎并不等待所有诺言解决

Question

嘿，我可能会在其他地方回答这个问题，但找不到适合我需求的答案。这段代码：

async function makeCharts(coin){
  let results = await Promise.all([getDailyData(coin), getCurrentData(coin)])
  makeCurrentLineChart(coin, results[1])
  makeHighLowLineChart(coin, results[0])
}

似乎并不等待结果数组被解析。两种图表方法有时不传递任何数据，有时效果很好。

这些是异步功能：

async function getDailyData(coin){
  let response = {}
  try{
    response = await axios.get('https://www.alphavantage.co/query?function=DIGITAL_CURRENCY_DAILY&symbol='+ coin +'&market=USD&apikey=' + APIKEY)
  }catch(err){
    response = err
  }
  let obj = { labels: [], highdata: [], lowdata: [] }
  const data = response.data['Time Series (Digital Currency Daily)']
  let i = 0
  for(let key in data){
    if(i == 21) break; 
    i = i+1
    obj.labels.push(key)
    if (data.hasOwnProperty(key)){
      obj.highdata.push(parseFloat(data[key]['2a. high (USD)']))
      obj.lowdata.push(parseFloat(data[key]['3a. low (USD)']))
    }
  }
  return obj
}

async function getCurrentData(coin){
  let response = {}
  try{
    response = await axios.get('https://www.alphavantage.co/query?function=DIGITAL_CURRENCY_INTRADAY&symbol='+ coin +'&market=USD&apikey=' + APIKEY)
  }catch(err){
    response = err
  }
  let obj = { labels: [], currentdata: [] }
  const data = response.data['Time Series (Digital Currency Intraday)']
  let i = 0
  for(let key in data){
    if(i == 100) break; 
    i = i+1
    obj.labels.push(key.split(' ')[1])
    if (data.hasOwnProperty(key)){
      obj.currentdata.push(parseFloat(data[key]['1a. price (USD)']))
    }
  }
  return obj
}

我看过丹尼尔·希夫曼（Daniel Shiffman）的诺言视频，这似乎与那里的逻辑相符：

我也在这里查看，并且makeCharts函数与“摘要”部分上方的语法相匹配：
