"Error exporting job state.... - Unknown Error" when doing a bulk update of Job States

Issue
I am using Jobs Bulk Update to update the Job State on selected job and getting the following error:
"Error exporting job state.... - Unknown Error"

Cause
For practices integrated with Xero Practice Manager, this occurs when Xero Practice Manager's API does not allow any more updates from FYI for a certain period of time and the Job update fails.

Solution
Bulk update 5 Jobs or less at a time. This will successfully update the Job State.
You can also select any Jobs that have failed and update the Job State on these individually.
