> Key: NIFI-12704
> URL: https://issues.apache.org/jira/browse/NIFI-12704
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.24.0, 2.0.0-M2
> Environment: Docker, RedHat 8
> Reporter: Stephen Jeffrey Hindmarch
> Assignee: endzeit
> Priority: Minor
> Time Spent: 1h
> Remaining Estimate: 0h

> My use case is I want to create a field called "original" which is the
> escaped string of my whole record. This will preserve the original contents
> of the message before I start transforming it.
> My expectation is that I should be able to use an UpdateRecord processor to
> create the field using RecordPath language.
> What actually happens is that when I use
> {code:java}
> escapeJson(/)
> {code}
> as the function the result is that the processor throws a Null Pointer
> Exception (NPE).
> Detail:
> For any input flow file containing JSON records, define an UpdateRecord
> processor with these settings.
> * Replacement Value Strategy = Record Path Value
> * /original = escapeJson(/)
> When the flow file is presented to the processor, the processor generates an
> NPE.
> For example, I present this record.
> {noformat}
> [{"hello":"world","record":{"key":"one","value":"hello","subrecord":{"key":"two","value":"bob"}},"array":[0,1,2]}]{noformat}
> If the escapeJson function is offered an existing field to escape then it
> works as expected. Stack trace as follows.
