I am getting this error
error: Entities and POJOs must have a usable public constructor. You can have an empty constructor or a constructor whose parameters match the fields (by name and type). public enum Measurement {

the enum will simply be a way to store answers from a dropdown.

@Entity(tableName = "bottles")
data class Bottle(
    @PrimaryKey (autoGenerate = true)
    val consumableID: String,
    @Embedded var prescription : Prescription?,
    @Embedded var measurement: Measurement?,
    @Embedded var reminder: Reminder?,
    var quantityInBottle: Int?,
    val expirationDate : Date?,
    var startDate : Date?,
    val cabinetID: String
)


enum class Measurement {
    MILLIGRAMS,
    SCOOP,
    GRAMS,
    OZ,
    TSP,
    TBS,
}

I have TypeConverters for measurement defined as

class MeasurementTypeConverters {
    @TypeConverter
    fun measurementToString(measurement: Measurement?) : String{
        return measurement.toString()
    }
    @TypeConverter
    fun  stringToMeasurement(string: String) : Measurement{
        return Measurement.valueOf(string)
    }
}
