MUI X: The Tree View component requires all items to have a unique `id` property.

Describe the bug

I am using Agentflow v2, with a LLM planner, Iteration module for spawning Sub Agents, and finally router with option to loop back to the first LLM module. When I run it on some iterations both interfaces in Executions and inside the Flow become white, and the following error pops up in the browser console:

MUI X: The Tree View component requires all items to have a unique id property.
Alternatively, you can use the getItemId prop to specify a custom id for each item.
Two items were provided with the same id in the items prop: "iterationAgentflow_0_23"

To Reproduce

1. Run a flow;
2. When the flow is marked as completed in Executions - open the flow;
3. The page is blank, and there is an error message in the browser console:

MUI X: The Tree View component requires all items to have a unique id property.
Alternatively, you can use the getItemId prop to specify a custom id for each item.
Two items were provided with the same id in the items prop: "iterationAgentflow_0_23"

Note, this error appears in different iterations, not _0_23 precisely and not in every test.
It appears to be a Race Condition.

Expected behavior

To show all the steps properly.

Hi, did you fix it? ( _ (

are you using the one from marketplace? it seems to work fine for me:

Hi @HenryHengZJ, I used initially that template, but then heavily modified and extended it to adapt to my specific needs (e.g. different models used, different tools and approach).

For some reason the MUY interface throws an error, and it is not each time - sometimes the flow completes OK.

I have the feeling this comes of race conditions between SubAgents.
