TypeError: Cannot read property '_prevProps' of undefined about why-did-you-render

[rosskevin]

I manually removed the .min from the package.json bundles so I could traverse the code more easily. Looks like related to loadable-components or Route...not sure, but I'm continuing to narrow it down now.

add

if (!this) {
  debugger;
}

to the render FN:

render(){
if (!this) {
  debugger;
}
      if(this._prevProps){
        options.notifier(getUpdateInfo({
          Component: ClassComponent,
          displayName,
          prevProps: this._prevProps,
          prevState: this._prevState,
          nextProps: this.props,
          nextState: this.state,
          options
        }))
      }

      this._prevProps = this.props
      this._prevState = this.state

      return super.render && super.render()
    }
