Cannot read property 'getRawIndex' of undefined

One-line summary [问题简述]

饼图未完全渲染，即饼图动态变化时，鼠标hover到饼图的扇区，报错Cannot read property 'getRawIndex' of undefined， 但不影响渲染以及后续使用

Version & Environment [版本及环境]

• ECharts version [ECharts 版本]: 4.1.0
• Browser version [浏览器类型和版本]: 70.0.3538.77
• OS Version [操作系统类型和版本]: mac

Expected behaviour [期望结果]

不输出该错误

ECharts option [ECharts配置项]

option = {
   tooltip: {
      show: true,
      formatter: (params) => {....},
  }
  series: [{
     name: '计数',
      type: 'pie',
      center: ['50%', '50%'],
      data: [{
       .......
       }]
   }]
  }
}

比较特殊的是 我的数据是远程获取，并且数据比较大，当整个饼图渲染完，并没有变化的时候，鼠标hover上去不会有什么错误，但是当数据还在加载的时候，饼图还在变化，这个时候鼠标hover上去会报错。
错误如下

Please provide a full example at jsfiddle or http://gallery.echartsjs.com/editor.html .
I tried to add animationDuration: 5000 to slow down the animation and hover on pie before the animation completed and cannot reproduce it.

不好意思 ，我们的场景比较复杂，不太好描述，如果单纯的写options，也确实不会出现这种问题，我想问下，因为我看到代码出错的地方是 var data = this.getData(dataType);这里为undefined，不知道是不是我姿势用的不对， 一般什么情况下 这里会undefined呢

I cannot tell from the provided information.
Please debug by yourself with ECharts repo node build/build.js.

e.target.dataType 为undefined

[ankushjamdagani]

Same thing happening for me too. I have debugged it to this function. Task appears to be null here. And this function is returning undefined.

Series.js

  getData: function (dataType) {
    var task = getCurrentTask(this);

    if (task) {
      var data = task.context.data;
      return dataType == null ? data : data.getLinkedData(dataType);
    } else {
      // When series is not alive (that may happen when click toolbox
      // restore or setOption with not merge mode), series data may
      // be still need to judge animation or something when graphic
      // elements want to know whether fade out.
      return inner(this).data;
    }
  }
