NiFi fails to start after setting sensitive parameter into non-sensitive property

My NiFi begins to start-up and after some time (before GUI comes on-line) it shuts down. In log appeares message like this one: org.apache.nifi.web.server.JettyServer Failed to start web server... The property cannot reference Parameter because Sensitive Parameters may only be referenced by Sensitive Properties.

Please, what I should do to be able to start NiFi and solve this?

To start NiFi with such mis-setup it is necessary to remove conflicting setting from flow. To do so:

  1. Backup your original flow - file <nifi-home>/conf/flow.xml.gz
  2. Extract file flow.xml from this archive
  3. Find problematic xml element using names referenced in error message and remove the offending value-line. So this:
    <entry>
      <key>Password</key>
      <value>#{ftp_password}</value>
    </entry>

becomes this:

    <entry>
      <key>Password</key>
    </entry>
  1. Repack archive and start NiFi - now it should come online
  2. This time set your sensitive values in a correct way :-)
