Caused by: java.lang.ClassCastException: class org.apache.avro.generic.GenericData$Array cannot be cast to class [J (org.apache.avro.generic.GenericData$Array is in unnamed module of loader 'app'; [J is in module java.base of loader 'bootstrap')
GenericDataArray treats the collection as list opposed to long[] array. Fixing the same.
