> This issue aims to fix a union avro type with more than one non-null value (for instance `["string", "null", "int"]`) the deserialization to a DataFrame would throw a `java.lang.ArrayIndexOutOfBoundsException`. The issue was that the `fieldWriter` relied on the index from the avro schema before null were filtered out.
