Hi,

We started receiving an exception while trying to invoke the Bulk API to create a job in our Sandbox.  We haven't had any issues before until now.  Our code is unchanged since the last time we touched it.  I was able to capture the request as well as the response.  The call to the SOAP service to log in works fine and returns a sessionID, but when we build the request to create a job it returns the 400 Bad Request response.  Once I stream the response out to get the details I get the following:

  <?xml version="1.0" encoding="UTF-8"?><error
   xmlns="http://www.force.com/2009/06/asyncapi/dataload">
 <exceptionCode>Unknown</exceptionCode>
 <exceptionMessage>Unknown exception in Async API. Please contact support with ID: 1190435897-34246 (361211693)</exceptionMessage>
</error>

Here is the request string we submit, nothing has changed here:
<?xml version="1.0" encoding="UTF-8"?>
    <jobInfo xmlns="http://www.force.com/2009/06/asyncapi/dataload">
        <operation>query</operation>
        <object>Account</object>
               
        <contentType>CSV</contentType>
    </jobInfo>

I've verified the endpoint that it is hitting as well, nothing has changed here either.

I've checked permissions on the Salesforce objects to verify select access, I've tried a couple of different user credentials in place of our API user that we set up with no luck.  Any help would be appreciated.
