Agentic Workflow returns duplicate responses intermittently

[Prabhu22ap]

Hi Community,

I am testing a ServiceNow Agentic Workflow and have observed that the agent occasionally returns the same response multiple times in the conversation, even though I expect only a single output.

The issue is intermittent and does not happen for every execution.

I would like to understand:

1. Is there a configuration to ensure that only one final response is returned to the user?

2. Can duplicate responses occur due to multiple node executions, retries, tool invocations, or streaming behavior?

3. Has anyone encountered this behavior in Agentic Workflows, and if so, how was it resolved?

Any guidance on troubleshooting steps or best practices would be greatly appreciated.

Thanks.

I am using default LLM.  I have 6 agents added to agentic workflow. Each agent is called once and after output is shown it will go to the next agent. I kept output to none in the agents, and concise to other and few agents only analyse, so no tools are added. 

In the agent roles, i have also mentioned to show the output only once as it is triggering multiple responses sometimes.
