Room DB: java.lang.reflect.InvocationTargetException

I am implementing Room database in my new app. When setting up the database I get this error:

* What went wrong:
Execution failed for task ':app:kaptStandardDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
   > java.lang.reflect.InvocationTargetException (no error message)

This is how my database class looks like:

    @Database(
  entities = [
    ExternalDataModel::class
  ],
  version = 1
)
@TypeConverters(Converters::class)
abstract class MyRoomDatabase : RoomDatabase() {

  abstract fun externalsDao(): ExternalsDao

  companion object {

    private const val DB_NAME_PREFIX = "myt_db_user"

    @Volatile
    private var instance: MyRoomDatabase? = null

    fun getInstance(context: Context): MyRoomDatabase{
      return instance ?: synchronized(sLock) {
        instance ?: buildDatabase(context, DB_NAME_PREFIX).also {
          instance = it
        }
      }
    }

    private val sLock = Any()

    internal fun close() {
      synchronized(sLock) {
        instance?.close().also {
          instance = null
        }
      }
    }

    private fun buildDatabase(context: Context, dbName: String): OneAccountRoomDatabase {
      return Room.databaseBuilder(context, MyRoomDatabase::class.java, dbName)
        .build()
    }
  }
}

Entity:

    @Entity(
  tableName = "externals",
)
data class ExternalDataModel(
  @PrimaryKey val id: String,
  val name: String,
  val profileImage: String? = null,
  val description: String,
  val multifactor: Boolean,
  @TypeConverters(Converters::class)
  val requestedData: List<ExternalField>
)

This is Converter:

class Converters {
  private var gson = Gson()

  @TypeConverter
  fun stringToExternalFieldlList(data: String?): List<ExternalField> {
    if (data == null) {
      return Collections.emptyList()
    }
    val listType = object : TypeToken<List<ExternalField>>() {}.type
    return gson.fromJson(data, listType)
  }

  @TypeConverter
  fun externalFieldToString(someObjects: List<ExternalField>): String {
    return gson.toJson(someObjects)
  }
}

When I remove @Database annotation the error is gone, so I thought maybe something is wrong with entity itself. Tried changing val to var, adding @ColumnInfo(name=…) but nothing helped.

–stacktrace gives this:

    FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptStandardDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
   > 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:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:kaptStandardDebugKotlin'.

Answer

Downgraded Kotlin from ‘1.4.10’ to ‘1.3.50’ helped.
