> Report my USER mailing list:
> Hi,
> I recently discovered some of our data has NULL values arriving in an
> ARRAY<STRING> column. This column is being consumed by Flink via the Kafka
> connector Debezium format. We seem to be receiving NullPointerExceptions for
> when these NULL values in the arrays arrive which restarts the source
> operator in a loop.
> Is there any way to not throw or to possibly filter out NULLs in an Array of
> Strings in Flink?
> We're somewhat stuck on how to solve this problem, we'd like to be defensive
> about this on Flink's side.
> Thanks!
