> While investigating [this SO question|https://stackoverflow.com/questions/54981540/nifi-recordreader-recordwriter-serialization-error-illegaltypeconversionexcep], it was discovered that Arrays of RECORD type (whether Record or Map objects) are not being handled correctly, and as a result, the fields may be incorrectly ignored or set to null.
> Arrays (especially those of Object[] type) should be handled during conversion by creating a new array of the converted objects (Record -> Map, e.g.).
