You need to delete the node, ensure your n8n version is updated, restart the instance once it updates, and readd the node.

(If you go to node settings you can see the version of the node for your refrence, but just follow the steps above and it should work!

Do not use sub-agents as tools.
They increase coupling, debugging difficulty, and unexpected side effects.
Modularize everything and invoke them as sub-workflows.
