In my Facebook application, when I call Parse.User.current().fetch(), Parse Server won't return sessionToken for that user as Parse API do. After that JS SDK will save that response (without sessionToken) into localStorage, which made all request after that not include sessionToken.
In my case, after call Parse.User.current().fetch(), I cannot call any cloud function because cloud code will check if the request is called by a logged-in user.
I have added two images, one is call fetch current user via Parse API, and one via Parse Server, 2 servers connected to the same database.
Response from Parse API

Response from Parse Server (missing sessionToken)
