I have the following class that I am using as a dynamodb item in Kotlin

@DynamoDbBean
data class Transaction(
    @get:DynamoDbPartitionKey
    val userId: Int,
    @get:DynamoDbSortKey
    val timestamp: Long,
    val ticker: String,
    val transactionType: Type)

val transactionTable =
    DynamoDBenhancedClient.table(MoneyBeacon.TRANSACTION_TABLE,
    TableSchema.fromBean(Transaction::class.java))

I get this error:

 java.lang.IllegalArgumentException: Class 'class db.aws.dynamodb.pojos.Transaction' appears to have no default constructor thus cannot be used with the BeanTableSchema

If I set this class up with a default constructor then I will have change it to var and allow the values to be nullable which I don't want to do. Any other solutions?
