Failed to decompress data for the AssetBundle

Hey guys,

I am trying to create an app which will download a scriptable object from a server online then load the mission according to data in the scriptable object.

So just to get a basic understanding of what needs to be done I have played a bit with unity's addressable package. For the server, I have temporarily uploaded a sphere prefab on Dropbox. (I am using Dropbox temporarily after reading this - https://www.yudiz.com/getting-started-with-asset-bundles-in-unity/)

But I am getting this error :

Error while downloading Asset Bundle: Failed to decompress data for the AssetBundle

Any fix??
