VAPI is converting my tool parameters to snake case for the call. This is the input I gave the assistant for this function. This is directly from the response to an assistant request.

json
{
  "type": "function",
  "function": {
    "name": "createEstimate-a1329",
    "description": "Create Estimate",
    "parameters": {
      "type": "object",
      "required": [],
      "properties": {
        "note": {
          "type": "string",
          "title": "Note"
        },
        "schedule": {
          "type": "object",
          "title": "Schedule",
          "required": [],
          "properties": {
            "endTime": {
              "type": "string",
              "title": "End Time"
            },
            "startTime": {
              "type": "string",
              "title": "Start Time"
            }
          }
        }
      }
    }
  }
}

During the call, the bot sees the parameters as end_time and start_time, breaking my connections. This was checked over multiple calls. Every single time, it treated startTime and endTime as snake_case. When asked directly (without leading it) what case the parameters are, it says snake case every time. A call ID is d64f08ea-906f-429f-a358-0e8b5020743d
