查看错误定位到 lottie-miniprogram/index.js的如图位置

使用代码如下，是完全按文档写。

wx.createSelectorQuery().in(this).selectAll('#welfare_lottie').node(res => {
 const canvas = res[0].node
 const context = canvas.getContext('2d')
 canvas.width = 144
 canvas.height = 144
 lottie.setup(canvas)
 this.ani = lottie.loadAnimation({
  loop: true,
  autoplay: true,
  path: 'https://img.picka.com.cn/mini-program/json/lottie.json',
  rendererSettings: {
    context,
  },
 })
 this.inited = true
}).exec()
