RailsでLoadErrorのUnable to autoload constant ''が出てきます

railsを起動しcisco merakiのダッシュボードからScanning APIのPOSTs URLを追加しようとURLを入れてrails側にGETリクエストを送り、それに対しRailsがValidatorの値をPOSTで送り返したところ、下記のエラーメッセージが出てきました。
app/models/personal_log.rbに問題があるようなのですが、ここには何も記述してなく原因がわからずどうアプローチしていいのかわかりません。

どうかお力を貸して頂きたいです。

app/models/personal_log.rbに問題があるようなのですが、ここには何も記述してなく原因がわからずどうアプローチしていいのかわかりません。

app/models/personal_log.rbに問題があるのではなく、PersonalLogクラスをロードしようとして、このファイルで定義されていることを期待してロードしようとしたけど失敗したことを意味しています。
PersonalLogを定義したapp/models/personal_log.rbファイルが必要です。
