Tool Variables Input Form Not Showing
# supporti
Issues
07/31/2025, 1:43 PMHey 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?
