WebGL asset bundles collider problem

I try to convert my webplayer project into webgl.
I have problem when try to load asset bundles with www class.
When load all browser give me error like this:

Could not produce class with ID 65

I see that code is relative to collider, so i delete collider from gameobject, resave asset bundle (without collider) and now app work.
Somebody can help me? I need collider attached to model…


here is the solution.

Try to switch off engine stripping in “Player settings”

When you build a game, builder remove all unused scripts, so if you use some scripts only in assetbundle hey will be removed from “Release file” as “unused”.
