Tool Variables Input Form Not Showing

Hey Vapi team, I’m running into what looks like a schema sync issue with my custom function tool. As per the attached screenshots:

I’ve defined the parameters via Visual Editor (e.g., ClientName, PhoneNumber, EmailAddress) and saved the tool. But:

The Test Tool panel shows an empty {} in the request body

The Workflow Tool node does not show the “Input” mapping form

I’ve also...

Rebuilt the tool from scratch

Used Visual Editor (not raw JSON)

Tried just one field (ClientName)

Cleared browser cache

Rebuilt the workflow

Tested across Chrome, Safari, and Incognito

Any way to fix this issue?
