Hello everyone,
I’ve encountered an issue — my workflow worked fine when using version 2.2 of the AI Agent node, but it started failing after updating to version 3(ver1.118.0). I believe this is a bug. More details can be found here.

In version 3 of the AI Agent node(ver1.118.0), the Code Tool sub-node cannot access variables from other nodes
