Node behavior: Repeated tool calls with identical arguments

These issues should be primarily resolved in version 1.72 (currently available) and completely fixed in 1.72.1 (scheduled for release tomorrow).

Please inform us if this is not the case!

Hi,
I've tested a couple of examples and it seems to work great!
Thanks a lot!
Happy end of the year

Thanks for confirming! You too

I'm still encountering an issue on version 1.73.1.

I have a straightforward workflow that includes one AI Agent and a sub-workflow designed to interact with BigQuery using an SQL Query.

When I pose a simple question to the Agent, I observe it generating various queries to find the answers. However, the sub-workflow consistently receives only the very first query generated.

The query tool's sole function is to pass along the {{ $fromAI(‘query’) }} variable, but it appears to always forward the initial query it produces, rather than subsequent ones.

Hello!

It appears you are invoking a sub-workflow. If I recall correctly, the fromAI function is exclusively available within Nodes as tools.

When using the Call n8n workflow tool, you can specify the value within the sub-workflow call description.

For instance, here's a snippet of my prompt:

You will send the following fields to the tool: issue_type, date, criticality, description and user_name

And the execute workflow trigger receives the following query:

Does this seem correct?
