custom generating command 'Command xxx appears to be statically configured for search command protocol version 1'

I am attempting to use custom generating command protocol version 2, but my command seems to be detected as version 1 still. commands.conf: > [datascrape] filename = xxx.py> chunked = true xxx.py: > @Configuration(type='events') class> xxxCommand(GeneratingCommand):> ...> def generate(self):> ... yield xxx> ... self.finish()> ...> @staticmethod> def foo(): Even if I replace the commands.conf config with the specified version 1 arguments, I still get the error message, even after splunk restarts. Thanks for any pointers
