Python × seleniumでのWebスクレイピング処理のIndexError: list index out of rangeエラー

前提

https://qiita.com/kazumatsukazu/items/5b7141c85fd85c7d1c0d
https://blowup-bbs.com/gcp-cloud-functions-python3/
上記サイトを参考に、ローカルでのWebスクレイピング作業をGCPに移行させたい。

実現したいこと

Cloud Functions上でheadress-chromeをPythonで動かし、ランダムなwikiの値を返す。

現状

※デプロイはできているっぽいが、関数のテストを実施するとエラーになる。
