> I am getting java.util.NoSuchElementException in QueryRecord under certain conditions using JsonTreeReader + JsonRecordSetWriter + a simple json event.
> Generating a simple flowfile with the following json using GenerateFlowFile:
> {{
> {"epoch":1642669279,"thing":[1234],"foo":"bar"}
> }}
> Using QueryRecord with the following dynamic properties work:
> {{SELECT * FROM FLOWFILE WHERE foo = 'bar'}}
> {{SELECT * FROM FLOWFILE WHERE foo LIKE 'ba%'}}
> However, using the following generates an error:
> {{SELECT * FROM FLOWFILE WHERE foo LIKE 'fo%'}}
> It appears it will fail if the WHERE clause does not find any matches in the
> flowfile.Removing {{"thing":[12345]}} from the json in the flowfile causes all 3 dynamic
> properties in QueryRecord to work.The error generated is:
