DSC EventLog errors every 10 mins on pull server

I’ve setup a DSC pull server using information from this URL: https://msdn.microsoft.com/en-us/powershell/dsc/pullserver
I’m pretty happy that I got it working - mof files appear to be distributed and acted upon.

However I am seeing a regular set of errors in the “Desired State Configuration / Operational” client event log. Three errors appear every 10 minutes in rapid succession:

Job {1E5A6D1C-5FCF-11E6-80F2-CE9EFA21E00F} : 
MIResult: 1
Error Message: 
Message ID: 
Error Category: 0
Error Code: 1
Error Type: 
Job {1E5A6D1C-5FCF-11E6-80F2-CE9EFA21E00F} :

Message ID: NULL
Error Category: 0
Error Code: 0
Error Type: NULL
Job DscTimerConsistencyOperationResult : 
DSC Engine Error : 
	 Error Message: NULL 
	Error Code : 1 

Have do I fix these errors?

I assume these are on the Pull Server? Can you send me the zip file that is generated using
New-xDscDiagnosticsZip cmdlet from xDscDiagnostics module (GitHub - dsccommunity/xDscDiagnostics: This module contains cmdlets for analyzing DSC event logs.)?
If you can upload the file somewhere and paste the URL, that would be great. Or if you want to send me the zip file - insivara@microsoft.com is my email.
