google-cloud-platform - Function が成功した (200 ステータスが返された) ときに Google Cloud Function を呼び出す Google Cloud Scheduler が 500 ステータスを取得する

Question

1 時間に 1 回、Scheduler ジョブで自分の関数を呼び出します。関数は問題なく動作し、毎回 HTTP 200 ステータスを返します。ただし、3 ～ 5 回の呼び出しごとに、Scheduler ジョブは HTTP 500 ステータスを返します。この問題の原因/修正は何ですか?

例: 関数ログが示している内容は次のとおりです。
