Why does Mini Program's drop-down refresh written in wepy framework appear to be loaded?

as shown in the figure, this causes me to pull down and bounce back very quickly. How can I solve this problem?

request interface code:

async getList() {...}
onLoad() {
  let that = this;
  that.getList();
}

drop-down refresh code:

onPullDownRefresh() {
  console.log("")
  this.onLoad();
  wx.stopPullDownRefresh()
}
