Steps to reproduce

Having 10 iteration nodes running in parallel with workflow as tools inside them, if 1 workflow fails inside one of the iteration nodes, the debug logs shows the error on all iteration nodes and all workflow tools. So it's not possible to debug.

✔️ Expected Behavior

Normal detailed logging, showing what workflow tool / iteration node that failed

❌ Actual Behavior

All nodes, even those who didn't fail, shows error.

Also the nodes that are inside the iteration node, shows as being outside of the parallel nested view.
