---------------------------------------
Hi [~hequn8128], hi [~fan_li_ya],
This issue was already addressed by another PR
(https://github.com/apache/flink/pull/7965/) that I just merged.
Sorry, I didn't notice there was another PR.
The approach is the same as [~hequn8128]'s. However, it does not include a
test. [~hequn8128], do you want to rebase your PR and adjust your test?
Thanks, Fabian

> We should catch the exception and enrich it with information about the
> affected field to make it more useful.
