Dao Error: Not sure how to handle query method’s return type //Android Kotlin Dev Diary

As I brush up on my Room database knowlege I came upon the following error while building my app:

WordDao.java:21: error: Not sure how to handle query method's return type (java.lang.Object). DELETE query methods must either return void or int (the number of deleted rows).

The solution:

Set Kotlin version to 1.6.10 then Room to 2.4.2 (Or use more recent compatible versions) in my top-level build.gradle file.
