I suspect that this is due to salesforce sending a response that this gem doesn't expect.

[Issue yatish27#54] Fix NilClass evaluation
d9ef244 
Occasionally, the results of either
`check_job_status` or `check_batch_status` return
nil. This commit adds conditions to protect
against evaluating a NilClass.

Error:
undefined method `[]' for nil:NilClass (NoMethodError)
