> The attached schema has top-level AVRO Union type. Whenever the client tries
> to deserialize the message it fails at parsing field - opt_amount, with stack
> trace -
> {code:java}
> Caused by: java.lang.ClassCastException: class java.nio.HeapByteBuffer cannot
> be cast to class java.math.BigDecimal (java.nio.HeapByteBuffer and
> java.math.BigDecimal are in module java.base of loader 'bootstrap')
