Description

For example, if using ${filename:substring(1, 20)} and the filename is only 15 characters, this will throw an Exception, which causes UpdateAttribute to yield and not penalize the FlowFile. Instead, it should catch this Exception and rollback with penalization and NOT yield, as this is a problem with the data, not a problem with the processor's ability to function at this moment.
