Hi there! 👋 I can see you've identified an issue with the JSON in the Custom Tools documentation. You're right - the JSON you shared is invalid. Looking at the provided JSON snippet, I can identify the issue. The

toolWithToolCallList

array contains an object that's improperly formatted. The problem is that the

server

property is positioned as a separate object in the array rather than being nested within the first object. Here's what's making it invalid:

json
"toolWithToolCallList": [
    {
        "type": "function",
        "name": "get_weather",
        "parameters": {
            "type": "object",
            "properties": {
                "location": {
                    "type": "string"
                }
            }
        },
        "description": "Retrieves the current weather for a specified location"
    },
    "server": { // <-- This should be inside the previous object, not a separate array item
        "url": "https://your-api-server.com/weather"
    },
    // ...
]

According to the information I found, the correct structure for

toolWithToolCallList

should have the

server

property nested within the same object that contains the function details. Based on [examples from the Vapi documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1339941602872918068), the proper format should look like: ```json "toolWithToolCallList": [ { "type": "function", "function": { "name": "get_weather", "parameters": { "type": "object", "properties": { "location": { "type": "string" } } }, "description": "Retrieves the current weather for a specified location" }, "async": false, "server": { "url": "https://your-api-server.com/weather" }, "messages": [], "toolCall": {
