使用UnityWebRequest加载cdn资源数据，代码如下

UnityWebRequest request = UnityWebRequest.Get(url);

            request.SendWebRequest();

            while (!request.isDone) {

            }

            if (request.result != UnityWebRequest.Result.Success) {

                return string.Empty;

            } else {

                return request.downloadHandler.text;

            }

调用后报错，如下：

exception thrown: TypeError: Cannot set property '1' of undefined,TypeError: Cannot set property '1' of undefined
