writeStringToMemory is deprecated When Loading Assetbundle on photon

Questions & Answers
1

I am loading a Scene from assetbundle in WebGl and unable to join or create random room and stuck on this error:

writeStringToMemory is deprecated and should not be called! Use stringToUTF8() instead!

I am using a node.js API to load assetbundel based on user data and to parse JSON I use SimpleJSON

In Editor its working fine.

I am using PUN2 and Unity 2019.20.f1

The code to build assetbundle

[MenuItem("Assets/Build AssetBundles")]
    static void BuildAllAssetBundles()
    {
        string assetBundleDirectory = "Assets/StreamingAssets";
        if (!Directory.Exists(Application.streamingAssetsPath))
        {
            Directory.CreateDirectory(assetBundleDirectory);
        }
        BuildPipeline.BuildAssetBundles(assetBundleDirectory, BuildAssetBundleOptions.None, EditorUserBuildSettings.activeBuildTarget);
    }

And the coroutine to load assetbundel

IEnumerator Loadmodel(string bundleUrl)
    {
        using (WWW web = new WWW(bundleUrl))
        {
            yield return web;

            AssetBundle remoteAssetBundle = web.assetBundle;

            if (remoteAssetBundle == null)
            {
                Debug.LogError("Failed to download AssetBundle!");
                yield break;
            }
            string[] scenePaths = remoteAssetBundle.GetAllScenePaths(); //loading all scene path
            Debug.Log(scenePaths);
            string sceneName = System.IO.Path.GetFileNameWithoutExtension(scenePaths[0]);

            PhotonNetwork.LoadLevel(sceneName);  

        }
        yield return null;
    }

The solution that work for me is Try Low MTU (MaximumTransferUnit) . The problem is Webgl is send more data to photon server in specific time than Editor.
when I add this line in my code all errors are gone .

loadBalancingClient.LoadBalancingPeer.MaximumTransferUnit = 500;

For more detail

Hope this will help other.
