Query using Bulk API

Hi all,


I'm trying to start a Job via the Bulk API to query the AccountHistory table, but I get this error:


'Unknown exception in Async API. Please contact support with ID: ###'


Same goes for LeadHistory, etc.  Are the History tables not supported in the Bulk query API?




Hello I have the same problem with all "_History" tables and NewsFeed table. Anyone knows where to contact support? Also, I've found this link This guy says about bug W-1133045 Anyone knows the place where I can read more about this bug? I'd like to know more about issue. Thanks.

I just ran into this one....   Has anyone heard back from sfdc on it?  The meta data indicates that it is queryable and there is no specific property in the metadata that indicates that it is not "BulkQueryable"


we are also facing the same issue..We are getting the same error when we are trying to fetch the result using bulk API for objects like account, contact etc.. But no errors on User.


Do post if anyone knows the exact cause and solution for the same.


I'm having also the same problem.

I'm getting the error when trying to bulk query all history tables.


Is there a solution? 

Or at least a way to know up front that the object cannot be query by bulk API?
