@ZNFY  Since you are exporting a flow definition of a process group, you'll need to utilize the MiNiFi toolkit to transform it in to the proper format that can be loaded by MiNiFi.   The MiNiFi-toolkit can be downloaded from here: https://nifi.apache.org/download/ (select "MINIFI' and click download link for Toolkit).   Execute: ./minifi-toolkit/bin/config.sh transform-nifi <exported flow definition> flow.json.raw​   Now edit the flow.json.raw file and edit the following property at start of file (value can not be 0.)  "maxTimerDrivenThreadCount":5  Now you can start your MiNiFi and it will create the flow.json.gz as it starts.
