Sync Service SDK / RunWithObject method

Shawn.Ferrier
over 3 years ago

Hello,

This seems like a long shot, but I thought I would try. Technically speaking, the Sync Service offers an SDK, of sorts. The CHM documentation was removed ages ago (is all Dell-branded), but it's still largely functional and I've used it here and there. I was taking a look at it recently because it offers the ability to run a workflow against a single object on-demand. In that old help file, there is even a Running a Workflow Step on a Specific Source Object topic with some sample code. Very exciting... but I've been experiencing inconsistent results, and seem to be constantly getting:

Exception calling "RunWithObject" with "1" argument(s): "Value cannot be null.
Parameter name: elementType"
At line:8 char:1
+ $result = $qcWorkflowStep.RunWithObject($sourceObject)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : FaultException

The log file hasn't really provided me any insight, either.

Just wondering if anyone else has tried anything along these or might have any ideas.

Thanks!

    With the utmost respect, I would question the efficiency of processing a single object on demand with the sync service?  Wouldn't it be faster to use a Change or Automation workflow within the Admin Service?  I say this because in my experience (and I am sure your's is the same), there's a ton of "spool up" overhead associated with the sync service - something which you don't have with a workflow within the Admin Service.  This overhead is OK if you are performing batch operations that are not time sensitive but for anything that I want to have have occur quickly, I typically would use an Admin Service workflow.

    You do have me curious though about the use case that took you in this direction.
