How to handle avro BYTES type in flink

[Catlyn Kong]

Hi fellow streamers,

I'm trying to support avro BYTES type in my flink application. Since
ByteBuffer isn't a supported type, I'm converting the field to an
Array[Byte]:

case Type.BYTES =>
  (avroObj: AnyRef) => {
     if (avroObj == null) {
       null
     } else {
       val byteBuffer = avroObj.asInstanceOf[ByteBuffer]
       val bytes = new Array[Byte](byteBuffer.remaining())
       byteBuffer.get(bytes)
       bytes
       }
     }

And in the table, I'm creating PrimitiveArrayTypeInfo[Byte] for this field.
I'm getting ArrayIndexOutOfBoundsException:

Caused by: java.lang.ArrayIndexOutOfBoundsException: 40

Does anyone have experience with deserializing BYTES type from avro and
make it compatible with the table api? Wondering if it's cause I didn't use
the correct type or maybe I need to verify if there's enough data left in
the source?

Any input is appreciated.

Thanks!
