I am getting following exception while starting the NiFi instance. Any insight will be helpful.

Is this a flow.xml.gz you copied from another instance of NiFi? All the sensitive properties inside the flow.xml.gz file are encrypted using the sensitive property defined in the nifi.properties file (If blank NiFi uses and internal default). If you move your flow.xml.gz file to another NiFi, the sensitive property value used must be the same or NiFi will fail to start because it cannot decrypt the sensitive properties in the file.

I didnt copy the flow.xml.gz but imported some templates which must have updated the flow.xml. Whats the fix to restart the NiFi instance?
