Description

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.
