    Hello guys,
    replace your PUT request to this code to fix the bug.

    public static UnityWebRequest Put(string uri, byte[] bodyData)
    {
    return new UnityWebRequest(uri, "PUT", (DownloadHandler) new DownloadHandlerBuffer(), bodyData == null || bodyData.Length == 0? null : (UploadHandler) new UploadHandlerRaw(bodyData));
    }

    Use the following code:

    protected virtual IEnumerator PostEmptyBody(string route)
    {
    var headers = new Dictionary<string, string>
    {
    { "Content-Type", "application/json" }
    };

    var packetToSend = JsonUtility.ToJson(string.Empty);

    var body = Encoding.UTF8.GetBytes(packetToSend);

    var www = new WWW(route, body, headers);

    yield return www;

    if (!string.IsNullOrEmpty(www.error))
    {
    Debug.Log(www.error);
    }
    }

    Cheers,
