i used this code for testing
from nifiapi.flowfiletransform import FlowFileTransform, FlowFileTransformResult class WriteHelloWorld(FlowFileTransform): class Java: implements = ['org.apache.nifi.python.processor.FlowFileTransform'] class ProcessorDetails: version = '0.0.1-SNAPSHOT' def __init__(self, **kwargs): super().__init__(**kwargs) def transform(self, context, flowfile): return FlowFileTransformResult(relationship = "success", contents = "Hello World", attributes = {"greeting", "hello"})
python 3.11 , java 21 and Apache nifi 2.0.0 M4
