------------------------------------
Summary: RecordPathResult may throw NPE
Key: NIFI-4340
URL: https://issues.apache.org/jira/browse/NIFI-4340
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.3.0
Reporter: Pierre Villard
When using UpdateRecord and indicating a path existing in the schema but
pointing to a null field, it'll throw a NullPointerException.
Basically, NPE is thrown at:
{noformat}
result.getSelectedFields().forEach(...)
{noformat}
or
{noformat}
recordPath.evaluate(record).getSelectedFields().iterator().hasNext()
{noformat}
Stack trace:
{noformat}
