Google Calendar Functions Work Directly, Error In Sub Workflow

Good morning all,

First post. So first, thank you for having me, and for hosting this forum.

I’m struggling to resolve an issue with a workflow that calls to a subworkflow.

Below is a pic of what I have, that works.

Credentials, everything, works fine.

Second workflow is pulling from sub_workflows. The first (search agent) works fine, returns chats via telegram.

The second subworkflow, calendar_tool, doesn’t work.

This is a pic of the sub_workflow that it’s using:

All tests are green, but it’s not working.

I need help. I’ve deleted everything, re-built everything twice now, tested all sorts of mods. I’m obviously missing something.

What other details would be helpful to troubleshoot this thing? Thanks in advance for your input.
