I am using tool cals strict functionality with this type schema: "unit": { "type": "string", "enum": [ "kg", "g", "l", "ml", "ud" ] }, But I am receiving an empty string instad. I expect it to just be the values of the enum or missing, but in this case VAPI is sending me an incorrect request para, which then fails the zod validation on my side.

Thanks for reporting this issue with the enum values in tool calls. Based on the information you've provided, I'd like to gather a bit more context to help diagnose the problem. Could you share more details about your configuration: 1. Which model are you using with VAPI (e.g., GPT-4, Claude, etc.)? 2. Are you using

parallel_tool_calls

in your configuration? (Since there's a [known conflict](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1326276427628154920) between

strict

and

parallel_tool_calls

) 3. Is this happening consistently with all enum values or only in specific scenarios? 4. Could you share a bit more of your schema definition, particularly how the

unit

property is positioned within the overall schema? 5. Have you tried any workarounds so far? This will help me better understand your specific situation and provide more targeted assistance. Sources: - [Issues with the
