Hi,   We've developed custom Python-based processors (GetCheckpoint, UpdateCheckpoint) for NiFi 2.0.0-M2 to handle checkpoint creation and updates and put it in    python/extensions/GetCheckpoint.py python/extensions/UpdateCheckpoint.py   These processors worked correctly in 2.0.0-M2. However, after upgrading to NiFi 2.1.0, we’re encountering the following issues:       All custom processor properties now display the message:     “Sensitive of the parameter does not match the sensitivity of the property”     — even though the properties were not marked as sensitive in the code.       When adding a new instance of the processor, properties appear correct, but state handling breaks.       We modified and rebuilt the processors and, when adding them freshly to a flow, they seem to work correctly without any errros. However, existing GetCheckpoint /UpdateCheckpoint still show the sensitivity mismatch warning.       Even for newly created flows, if we simply change the processor version (    class ProcessorDetails:         version = '2.3.0' to     class ProcessorDetails:         version = '2.4.0'), the same sensitivity error returns.   Questions:       What is the correct process for upgrading or modifying custom Python processors ?     What is the correct way to Upgrade NiFI with custom processrs in place?       Is there a way to avoid manually replacing every instance of the processor across all existing flows?     Any insight or recommendations would be appreciated.   Thanks! ...
