----------------------------------
Summary: UpdateRecord fails to write schema when the record
writer's Schema Access Strategy is set to Inherit Record Schema
Key: NIFI-7043
URL: https://issues.apache.org/jira/browse/NIFI-7043
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.10.0
Reporter: Andre Araujo
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.
