You may get the following error if a job runs but does not download a submission:
Get Submission Error
System.ApplicationException: GetSubmissionNext
Could not find a part of the path 'C:\ProgramData\doForms\Sync And Save\1.2.1\XXX\Sub\'.
The path referenced is created the first time a submission is downloaded, so the error will be resolved as soon as the job successfully downloads a submission.
Present in version 1.2.1. Fixed in version 1.2.2
