I get the following error when trying to get the addressable data and instantiate an object.

But when I check the Json file on the server data folder outside assets,which I upload later into github webpage I can see the bundle there.I don’t know why the error showing - HTTP/1.1 404 Not Found. as the data is still there in the Json file(Parts of the json file given beow).

From one scene I login and reach another scene. So in that scene there is an empty GameObject where I attach the below script.At start I am trying to do the AsyncOperation.
I believe in the Start method itself the exception is encountered.

void Start()
    {
       // 'Label name given------ 'Models'
        Addressables.LoadAssetsAsync<GameObject>("Models", OnLoadDone);
 
    }

//Initially just trying to print names of the GameObjects
    private void OnLoadDone(GameObject obj)
    {
        LoadedAssets.Add(obj);

        Debug.Log("Count  " + loadedAssets.Count);
        for (int i = 0; i < loadedAssets.Count; i++)
        {     
            Debug.Log("Load Assets name " + loadedAssets[i].name);
            //Instantiate(loadedAssets[i]);
        }
    }

Let me see if the team has any guidance. Which version of Addressables are you on?
