Not sure if the right channel I am seeing tools call from UI failing with 400 as type is not being passed

{
  "message": [
    "property server should not exist",
    "property function should not exist",
    "type must be one of the following values: transferCall, endCall, dtmf, make, ghl, function",
    "type must be a string"
  ],
  "error": "Bad Request",
  "statusCode": 400
}

Also I see UI making calls to https://staging-api.vapi.ai/tool
