Seems that FunctionTool now includes some mandatory properties that seems vapi internal ones: id, orgId, createdAt, updatedAt

export interface FunctionTool {
  /**
   * This determines if the tool is async.
   *
   * If async, the assistant will move forward without waiting for your server to respond. This is useful if you just want to trigger something on your server.
   *
   * If sync, the assistant will wait for your server to respond. This is useful if want assistant to respond with the result from your server.
   *
   * Defaults to synchronous (`false`).
   * @example false
   */
  async?: boolean;
  /**
   * These are the messages that will be spoken to the user as the tool is running.
   *
   * For some tools, this is auto-filled based on special fields like `tool.destinations`. For others like the function tool, these can be custom configured.
   */
  messages?: (ToolMessageStart | ToolMessageComplete | ToolMessageFailed | ToolMessageDelayed)[];

  server?: Server;
}

I should not have to implement it when dealing with a transiant assistant.
