    Comment: was deleted

(was: [~asdaraujo], I tried to reproduce the issue by using the attached UpdateRecord.xml template (with Schema Access Strategy set to Inherit Record Schema) but did not get any exception.

input: [\{"id":1,"response":{"now":null}}]

output: [\{"id":1,"response":{"now":null},"new":"1"}] 

So please provide more details about this issue to reproduce so that I can check and fix if any issue in Nifi code. Thanks.)

> When using an UpdateRecord processor with JsonRecordSetWriter, with Schema Access Strategy set to Inherit Record Schema, I get the exception shown below.
> This is a regression. The same flow works on NiFi 1.9.x without problems.
> As a workaround, if I change the record writer's to get the schema directly from Schema Registry, instead of inheriting it, the flow works fine.
