There is indeed a bug here, whereby the task never completes instead of posting an exception.

The exception that should appear is as follows:

Cannot load type 'UserQuery+VideoDetails' from cache.
Add the [Serializable] attribute to this type to make it cacheable.

If you add that attribute to your VideoDetails class, it will run correctly.

This is now fixed in the latest beta, so in this scenario you will now see a helpful error message rather than a non-completing task.
