Maximum recursion depth exceeded

[pablo-secu]

Hi,

I created a simple splunk app to test splunk SDK, it works but I get an error when there are lots of events (~20000):

RuntimeError: maximum recursion depth exceeded while calling a Python object

I have already checked the python recursionlimit (= 1000 by default)

Here my code:

@Configuration()
class test(ReportingCommand):

    """  TODO

    ## Requirements:
        TODO
    ## Description:
        TODO

    ## Syntax:
        TODO

    ## Example:
        TODO

    """

    @Configuration()
    def map(self, events):
        return events

    def reduce(self, events):
        events_list = list(events)
        event={}
        for evt in event_list:
            event["test"]=evt
            yield event

dispatch(test, sys.argv, sys.stdin, sys.stdout, __name__)

Here the error:

The error seems to come from splunklib.

Thanks

Hi @pablo-secu , We are not able to repro this issue on our end. We have used the latest version of SDK and Splunk enterprise.

Please share commands.conf details for the app. Also please try using the latest version of SDK and Splunk and let us know if the issue still persists.
