Is there any way to automatically create an xmpp user when an agent is spawned?

SPADE version:3.1.3
Python version:3.7
Operating System:Ubuntu
XMPP Server:Prosody

Description

I plan to write a module that dynamically creates agents based on the tasks that are assigned to them. Since the IDs of the agents are going to be generated on the fly, based on their tasks, I am wondering if there is any way to create the agents without having to predefine their JIDs on the server.

What I am to do (in pseudocode)

for i in range(num_of_agents()):
        jid = create_id() #This creats an jid like 'task319@localhost' which is not already present on prosody localhost VirtualHost
        agent = myAgent(jid, "fake_password")
        agent.start()

What I did

As far as I understood from the document, the JIDs need to be defined first on the server in order to be used in agent creation. When I previously create an account with jid agent1@localhost on the server, agent creation is done smoothly with no errors. However, when I try to change the jid to something not predefined on the server, like agent2@localhost, I get the following error, though I have set allow_auto_registration flag on the Prosody's config file to true:
