Start with the supplied Spark 3.5 and Hudi 0.15 setup, then trace the failing write through HoodieMergeHandle.writeToFile and HoodieAvroParquetWriter.writeAvro. Reproduce the append using the provided CDC JSON, snapshot schema, and parquet.avro.write-old-list-structure settings. Done means the null-containing array case has a verified outcome without the reported NullPointerException.
