Hi,

Thanks for reporting this.

This is a know issue to be fixed in the upcoming 1.3.1: https://issues.apache.org/jira/browse/FLINK-6844.

Regards,

Gordon

Thanks for sharing ticket reference. Is there any time line as this is blocker?

[Tzu-Li (Gordon) Tai]

AFAIK, the release process for 1.3.1 should hopefully start within the next days.

There’s already a few critical fixes on the waiting list.

Any update when 1.3.1 will be available?

Our current copy is 1.2.0 but that has separate issue(invalid type code: 00).
