I am implementing a project where i need to pass sensor data to room database. I am using arrayLists to store the different type of sensors. Here is the actal code from the project:

package com.example.sensorsapp.RoomDB

import androidx.room.ColumnInfo
import androidx.room.Entity
import androidx.room.PrimaryKey
import androidx.room.TypeConverter
import com.google.gson.Gson
import com.google.gson.reflect.TypeToken

@Entity(tableName = "sensor_data_table")
data class SensorData(

    @PrimaryKey(autoGenerate = true)
    @ColumnInfo(name = "sensor_data_id")
    var id : Int?,

    @ColumnInfo(name = "sensor_accelerometer_sensor")
    var accelerometer_sensor_data : String?,

    @ColumnInfo(name = "sensor_temperature_sensor")
    var temperature : String?,

    @ColumnInfo(name = "sensor_gyroscope_sensor")
    var gyroscope : String?,

    @ColumnInfo(name = "sensor_linear_acceleratior_sensor")
    var linear_acceleration : String?,

    @ColumnInfo(name = "sensor_orientation_sensor")
    var orientation : String?,

    @ColumnInfo(name = "sensor_rotation_sensor")
    var rotation : String?,

)


class SensorDataTypeConverter() {


    @TypeConverter
    fun fromArrayList(list : ArrayList<ArrayList<Float>>) : String
    {
        return Gson().toJson(list)
    }

    @TypeConverter
    fun fromArray(list :ArrayList<Float>) : String
    {
        return Gson().toJson(list)
    }
}

Here is an instance of the code where i store the data to the database instance by using the repository functions:

            sensorData.id = 1
            sensorData.rotation = sensorDataTypeConverter.fromArrayList(rotationAllValuesForStore)
            GlobalScope.launch(Dispatchers.IO) {
                sensorRepository.update(sensorData)
                delay(5)

I am getting errors from the compiler which show as follows (and of which i have not been able yet to decipher which part i need to fix…)

Here are the errors:

Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
   > java.lang.reflect.InvocationTargetException (no error message)

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
