I followed this tutorial: Getting started with MiNiFi
Therefore, there is a input port in my root process group and a process group for MiNiFi. The MiNiFi Process Group, contains a Tail File Processor, a Remote Process Groupand a Connection between them.
Inside the MiNiFi Process Group I'm saving the Template, after this I download it from the Templates List and run the command:
minifi-toolkit-0.5.0\bin\config.bat transform minifi\MiNiFi2.xml minifi\minifi_config\config.yml
But it fails and says:
The JAVA_HOME environment variable is not defined correctly.
Instead the PATH will be used to find the java executable.
There are validation errors with the template, still outputting YAML but it will need to be edited.
Connection with id 10de7342-41ef-37a5-0000-000000000000 has invalid destination id 9b02eb45-3c2d-3fb4-91cf-880d5038c0cd
I re-created everything and the issue still exists.
This is my Template:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<template encoding-version="1.3">
