Critical UI Bug: Unable to Edit Tool Parameters in Workflow Node

Hello Vapi Team,

I am facing a critical issue where I am unable to configure the parameters for a Tool node within the Workflow builder.

Problem Description:

I have a configured Tool (e.g., Google_checar_disponibilidade) with parameters (rota, data_consulta).

In the Workflow editor, I add a Tool node.

I select the Google_checar_disponibilidade tool from the "Select Tool" dropdown.

At this point, the UI is supposed to provide a way to map workflow variables to the tool parameters (rota and data_consulta). However, no such interface appears.

There is no gear icon, "edit" button, or parameter fields visible on the tool card inside the node. Clicking the card does nothing. I am completely blocked from configuring the tool's parameters.

What I have tried:

Reloading the page.

Logging out and logging back in.

Deleting and recreating the Tool node multiple times.

This seems to be a UI bug that prevents the parameter mapping interface from appearing. As a result, I cannot pass dynamic data (like a date extracted from the user's utterance) to my n8n backend, making my workflow non-functional.

Could you please investigate this issue with the Workflow UI? The ability to configure tool parameters is critical.

Thank you.

Pedro Sampaio.
