Question

Unlike previous questions like TypeError: argument of type 'int' is not iterable there doesn’t seem to be an immediately obvious indexing problem in my case.

In the code below, testcfg.agents is a list of hostnames and/or IP addresses, and testcfg.port is the port which xmlrpc calls should use. The DSEvent class models events in Active Directory, and DSEvent.eventcommand is a list containing a command and its parameters (passed through xmlrpc calls to an agent, which executes it using the subprocess module.)

# Create a list of agents to process events from
agent_list = []
for a in testcfg.agents:
    agent_list.append(xmlrpc.client.ServerProxy("http://" + a + ':' + testcfg.port))

# Initial user creation:
for j in range(5):
    init_event = DSEvent(type = 'add', is_important = True)
    agent_eB = random.choice(agent_list)
    agent_eB.execute(init_event.eventcommand) # This line throws the fault described below!

The exact exception I’m getting is (with various tracebacks into the module stripped out):

xmlrpc.client.Fault: <Fault 1: "<class 'TypeError'>:argument of type 'int' is not iterable">

I can’t understand where this fault might be coming from. While init_event.eventcommand is an iterable object (a list) I’ve passed and returned iterable objects via xmlrpc in other code without encountering this error. I’ve checked for accidental variable reuse, and I don’t think that’s the problem either. I’d really love some help here!

For reference, here’s the full traceback for this error:

I think I’ve solved this, at least partially. Apparently remote functions only take a tuple of arguments. Changing

agent_eB.execute(init_event.eventcommand)

to

agent_eb.execute((init_event.eventcommand,))

seems to have fixed this particular error.
