taro cli 1.2.22升级到1.2.26后小程序运行报错 Cannot read property 'id' of undefined

问题描述
[问题描述：站在其它人的角度尽可能清晰地、简洁地把问题描述清楚]
taro cli 1.2.22升级到1.2.26后，原生小程序先运行taro convert，然后运行 npm run dev:weapp后，在原来小程序onLoad函数里面如果存在参数op，想获得op里面的值会报错，Cannot read property 'id' of undefined
复现步骤
[复现问题的步骤]
1.taro convert
2.npm run dev:weapp
3.运行编译后的代码

[或者可以直接贴源代码，能贴文字就不要截图]

// 这里可以贴代码
小程序源码
Page({
  data: {

  },
  onLoad: function (op) {
    let id = op.id
    console.log(id)
  }
})


taro convert后的代码：
import { Block } from '@tarojs/components'
import Taro from '@tarojs/taro'
import withWeapp from '@tarojs/with-weapp'

@withWeapp('Page')
class _C extends Taro.Component {
  state = {}
  componentWillMount = op => {
    let id = op.id
    console.log(id)
  }
  config = {}

  render() {
    return <Block>123</Block>
  }
}
