damccorm opened a new issue, #19640: URL: https://github.com/apache/beam/issues/19640
In Beam UDF, is it feasible to return a list? For example, the UDF function is defined as (input) String -\> (output) List<String\>, ```public static class UDF implements SerializableFunction<String, List<String\>\>``` I got a nullpointerexception if a list is returned.
