Hi @Mark_S

Thanks for posting here and welcome to the community! 🎉

We’ve already merged a fix for this bug and it should be released soon.

> <https://github.com/n8n-io/n8n/pull/11397>
>
> \## Summary
> This fixes an issue with resolving \`$fromAI\` expression when combine…d with \`noDataExpression\` and \`evaluateExpression\`. Because we're calling \`.execute\` of the wrapped tool node directly, the execute functions(\`getExecuteFunctions\`) would get created with references to the root node, and the root node's name would be passed in \`evaluateExpression\`. 
> To fix this, I changed \`evaluateExpression\` to be a named function so that it could access the current node's context and use \`this.getNode().name\` to get the node's name to resolve the expression.

Hello!  
Thank you for response. I updated my version and have new error. Agent trying to run simple query that works well with PostgreSQL node but fails with tool.
