Assetbundle loading show Received no data in response in unity 2019.2.9

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:

Code (CSharp):

1.  IEnumerator DependancyAssetBundleLoader()
2.         {
3.  
4.             www = UnityWebRequestAssetBundle.GetAssetBundle(bundleURLForDependency);
5.            // www.chunkedTransfer = false;
6.  
7.             yield return www.SendWebRequest();
8.             AssetBundle bundleDependancy = ((DownloadHandlerAssetBundle)www.downloadHandler).assetBundle;
9.  
10.             if (www.error != null)
11.             {
12.  
13.                 //Debug.LogError("assetBundleURL : " + bundleURLForDependency);
14.                 Debug.LogError("response code : " + www.responseCode);
15.              
16.                 Debug.LogError("www error : " + www.error);
17.                 www.Dispose();
18.                 www = null;
19.                 yield break;
20.  
21.             }
22.         }

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 :

Code (CSharp):

1.  IEnumerator DependancyAssetBundleLoader()
2.         {
3.             www = UnityWebRequestAssetBundle.GetAssetBundle(bundleURLForDependency);
4.             www.SendWebRequest();
5.  
6.             while (!www.isDone)
7.             {
8.                 yield return null;
9.  
10.             }
11.  
12.             AssetBundle bundleDependancy= DownloadHandlerAssetBundle.GetContent(www);
13.  
14.             if (www.error != null)
15.             {
16.                 //Debug.LogError("assetBundleURL : " + bundleURLForDependency);
17.                 Debug.LogError("response code : " + www.responseCode);
18.            
19.                 Debug.LogError("www error : " + www.error);
20.                 www.Dispose();
21.                 www = null;
22.                 yield break;
23.             }
24.         }

 

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

Code (CSharp):

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

 

Are you sure that your url bundleURLForDependency is working properly?

 

Yes, indeed when i am putting this url in browser, my gets download.

 

Maybe i have a plugin xmlhttpReqeust inside asset and outside asset folder that creating problem? But i delete inner plugin folder still the same problem
