What model do you select for the AI Agent Node ?
Maybe is not compatible with the version of the node itself, not the n8n version.

Please update @n8n/nodes-langchain Agent Node to the latest version (v3).
Current version is 2.2 and it does not support modern OpenAI models.

im experiencing the same problem

In my multi-agent solution , for me, this issue occurs on ‘AI Agent Tool’ (v2.2) not being compatible with ‘OpenAI Chat Model‘ node v1.3.

I am using a workaround to use v1.2 of ‘OpenAI Chat Model‘ node with the AI Agent Tool node. You can do this by first design a flow in editor, then downloading the JSON for this flow, manually editing the ‘OpenAI Chat Model‘ node version used with ‘AI Agent Tool‘ to v1.2, and then importing this JSON in as a new workflow.

yeah, but how? Just use a new AI Node? I don’T know a way to update a single node
