Assetbundle loading show Received no data in response in unity 2019.2.9

Unity Engine

Recently I have converted my unity 2019.1.0 project into unity 2019.2.9 and its is webgl project. In the project i am using asset bundle and here is the snippet to load the bundle:

 IEnumerator DependancyAssetBundleLoader()
        {
  
            www = UnityWebRequestAssetBundle.GetAssetBundle(bundleURLForDependency);
           // www.chunkedTransfer = false;
  
            yield return www.SendWebRequest();
            AssetBundle bundleDependancy = ((DownloadHandlerAssetBundle)www.downloadHandler).assetBundle;
  
            if (www.error != null)
            {
  
                //Debug.LogError("assetBundleURL : " + bundleURLForDependency);
                Debug.LogError("response code : " + www.responseCode);
              
                Debug.LogError("www error : " + www.error);
                www.Dispose();
                www = null;
                yield break;
  
            }
        }

I don’t know what went wrong with the asset bundle loading and now i am getting this error:

Received no data in response

I logged the response code and it 0.

Can you try :

 IEnumerator DependancyAssetBundleLoader()
        {
            www = UnityWebRequestAssetBundle.GetAssetBundle(bundleURLForDependency);
            www.SendWebRequest();

            while (!www.isDone)
            {
                yield return null;

            }

            AssetBundle bundleDependancy= DownloadHandlerAssetBundle.GetContent(www);

            if (www.error != null)
            {
                //Debug.LogError("assetBundleURL : " + bundleURLForDependency);
                Debug.LogError("response code : " + www.responseCode);
           
                Debug.LogError("www error : " + www.error);
                www.Dispose();
                www = null;
                yield break;
            }
        }

I tried it and it producing an error:
InvalidOperationException: Received no data in response
in this line

 AssetBundle bundleDependancy = (DownloadHandlerAssetBundle.GetContent(www));
