I need to pass vararg args: Any down the function stack, in order to format later a String. However I keep getting IllegalFormatConversionException

logDebug("WindowRef %08X", ref.id) // ref.id is an Int

fun logDebug(fmt: String, vararg args: Any) {

   val toAppend = fmt.format(args) // IllegalFormatConversionException
   ...
}

Try to pass them with the spread operator: *args

it worked..

why is this necessary since format also accept vararg?

vararg Any is not a type in itself, it becomes an Array<Any> once used, so you need to pass this array using the spread operator *
