I am using NiFi 2.0 that supports python scripts directly from a working directory, after I add my custom processor to the canvas, an error “Processor invalid because initializing runtime environment for the processor” is indicated in each custom processor. I have already installed Java JDK 21, python 3.11 and all the requirements specified in the official documentation. How can I resolve this?

I created a Python Nifi Processor just as in the standard python documentation. This is NOT an ExecuteScript processor. I am able to load the python processor but when I click the Configure Processor -> Relationships tab, I see no relationships there. This renders the Python processor useless. We cannot forward the resulting flowfile to any other downstream processors. The Error I get when trying to do so is -> “WriteHelloWorld’ does not support any relationships.
