Android Room in Kotlin 1.7.0 When updating to Kotlin 1.7.0, since it's required by the latest version of Jetpack Compose, I found out that Room was no longer working. I was using kapt as my annotation processor, and the compiler was throwing error messages such as: [*] error: Query method parameters should either be a type that can be converted into a database column or a List / Array that contains such type. You can consider adding a Type Adapter for this.
