I'm trying to run miniFi in ubuntu. When I try to start miniFi, I got following error in bootstrap and app log.

@Jagapriyan

The exception is telling you that the following properties were not configured in the bootstrap.conf file for your MiNiFi:

nifi.minifi.sensitive.props.key= nifi.minifi.sensitive.props.algorithm=

Hi,

The errors indicate that your miniFi configuration has some issues. Specifically, you need to set a value for nifi.sensitive.props.key in your nifi.properties file. Also, check the flow configuration file for any misplaced elements like ‘maxConcurrentTasks’ and ‘networkInterface’, and correct them according to the schema.
