[jira] [Resolved] (MINIFICPP-1196) MiNiFiCPP-BUG: Failed to
initialize and start ExampleProcessor.py
[ https://issues.apache.org/jira/browse/MINIFICPP-1196?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
James Medel resolved MINIFICPP-1196.
------------------------------------
Resolution: Fixed
I figured out why the ExampleProcessor.py was not starting. It turned out my script file path specified in the config.yml file was wrong. Once I corrected it, the python processor worked.

> I am working on creating custom MiNiFiCPP Python Processors, my processors were failing to start, so I tried the ExampleProcessor.py from the repo and dropped it into my flow. When I run my flow, I receive the error message:
> {color:#0747a6}[2020-04-17 18:29:10.807] [org::apache::nifi::minifi::core::ProcessGroup] [error] Failed to start processor 54d61268-80d9-11ea-a76f-022edbf4da95 (ExampleProcessor): Could not correctly in initialize ExampleProcessor{color}
> I also receive warning message:
> {color:#0747a6}[2020-04-17 18:29:10.779] [org::apache::nifi::minifi::core::ConfigurableComponent] [warning] Could not find property Script File{color}
> I placed the ExampleProcessor.py into the minifi-python/ directory, then specified the Script File path for ExecutePythonProcessor in my config.yml file.
> I followed the instructions at *Apache NiFi - MiNiFi - Python Processors Readme*: [https://github.com/apache/nifi-minifi-cpp/tree/master/extensions/script]
> I used *ExampleProcessor.py*: [https://github.com/apache/nifi-minifi-cpp/blob/master/extensions/script/ExampleProcessor.py]
>
> Any help with getting this Python Processor to work would be greatly appreciated.
