Facebook Canvas unable to get profile picture

First time using Facebook Unity SDK, and it was able to download user’s profile picture fine in Editor. However when I tried to test it on Facebook Canvas, it wasn’t able to download it.

You are trying to load data from a www stream which had the following error when downloading.
Failed downloading

Why did that happen?

I am using 5.0.4 of the SDK

Looks like a bug that is being currently worked on: Log into Facebook
