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
